Abstract: CHEK2 is a well-established breast cancer susceptibility gene. The most frequent pathogenic CHEK2 variant is 1100delC, a loss-of-function mutation conferring 2-fold risk for breast cancer. This gene also harbors other rare variants encountered in the clinical gene panels for hereditary cancer. One of these is CHEK2 c.1312 G > T, p.(Asp438Tyr) in the kinase domain of the protein, but due to its rarity its clinical significance for breast cancer predisposition has remained unclear. Here, we tested the prevalence of CHEK2 p.(Asp438Tyr) allele showing enrichment in the Northern Finnish population, in a total of 2284 breast cancer patients from this geographical region. Genotyping was performed for DNA samples extracted from peripheral blood using high-resolution melt analysis. Fourteen CHEK2 p.(Asp438Tyr) carriers were identified (14/2284, 0.6%, P = 0.67): two in the cohort of breast cancer cases with the indication of inherited disease susceptibility (2/281, 0.7%, P = 1.00) and twelve in the breast cancer cohort unselected for the family history of disease and age at disease onset (12/2003, 0.6%, P = 0.66). This frequency did not differ from the frequency in the general population (10/1299, 0.8%). No CHEK2 p.(Asp438Tyr) homozygotes were identified. Our results indicate that CHEK2 p.(Asp438Tyr) carriers do not have an increased risk for breast cancer and the classification of the CHEK2 p.(Asp438Tyr) variant can be changed from the variant of uncertain significance (VUS) to likely benign for breast cancer.

Abstract: TINF2 is a critical subunit of the shelterin complex, which protects and maintains the length of telomeres. Pathogenic missense and truncating TINF2 mutations are causative for dyskeratosis congenita (DC), a rare, dominantly inherited bone marrow failure syndrome characterized by mucocutaneous abnormalities and cancer predisposition. Recent reports indicate that specific TINF2 truncating mutations act as high penetrance cancer predisposition alleles outside DC context, including breast cancer in their tumor spectrum. Here, we have evaluated the role of germline mutations in TINF2 and other shelterin genes in inherited breast cancer susceptibility using exome sequencing data from 98 Northern Finnish breast cancer cases with indication of inherited disease predisposition as a discovery cohort. A single protein truncating variant, TINF2 p.Tyr312Ter, was identified in one of the cases (1/98), and four more carriers were observed in the subsequently genotyped unselected breast cancer cohort (4/1904). None of the carriers were reported to have DC. TINF2 p.Tyr312Ter resulted in stable short form of mRNA transcript, and normal telomere length has been indicated by a recent report. Although recurrent in cases (total of 5/2095), TINF2 p.Tyr312Ter is also present in Finnish population controls (8/12,517), and the observed 4-fold higher frequency in cases falls at most into the range of moderate breast cancer risk alleles (OR 3.74, 95% CI 1.22–11.45, p = 0.029). Current results indicate that not all TINF2 truncating variants are high cancer risk alleles and add further evidence that different TINF2 mutations can have very diverse effects on the disease phenotype.

Abstract: Breast cancer is the most common malignancy among women, and the risk of developing the disease is strongly influenced by inherited predisposing mutations. Genes such as BRCA1, BRCA2 and PALB2 harbor variants that confer a high breast cancer risk, but despite extensive research, only about half of the hereditary component of the disease has been uncovered. The identification of novel predisposing alleles is imperative, as it enables better genetic counseling for the mutation carrier families and earlier cancer diagnosis. The first aim of this study was to find rare, deleterious breast cancer predisposing mutations using whole-exome sequencing of 98 Northern Finnish breast cancer cases with indication of inherited disease susceptibility. The second aim was to analyze the whole-exome sequencing data for ultra-rare protein truncating variants in shelterin complex genes and to assess their role in inherited breast cancer susceptibility. The third aim was to evaluate the prevalence and significance of CHEK2 p.Asp438Tyr, a rare missense mutation enriched in North Ostrobothnia and classified as a variant of unknown significance. Whole-exome sequencing revealed a recurrent splice acceptor mutation SERPINA3 c.918‐1G>C, which showed association with breast cancer in both hereditary and unselected cohorts (p = 0.006, OR = 5.1 and p = 0.009, OR = 2.8, respectively). The mutation was also enriched among medullary breast cancer cases, which is a rare tumor subtype (p = 0.000014, OR = 42.9). These results suggested that SERPINA3 c.918‐1G>C is a moderate-risk breast cancer allele. One protein truncating variant, p.Tyr312Ter, was discovered in shelterin complex gene TINF2. It had a 4-fold frequency in cases (0.24%, 5/2095) compared to controls (0.06%, 8/12 517) (p = 0.029, OR = 3.74). The results indicated that TINF2 p.Tyr312Ter is at most a moderate-risk breast cancer allele, even though similar mutations in TINF2 have been reported to result in high cancer risk an, Tiivistelmä Rintasyöpä on naisten yleisin syöpä ja sairastumisriskiin vaikuttavat erityisesti perinnölliset alttiustekijät.

Abstract: The fluorescence in situ hybridization (FISH) technique plays an important role in the risk stratification and clinical management of patients with chronic lymphocytic leukemia (CLL). For genome-wide analysis, FISH needs to be complemented with other cytogenetic methods, including karyotyping and/or chromosomal microarrays. However, this is often not feasible in a diagnostic setup. Optical genome mapping (OGM) is a novel technique for high-resolution genome-wide detection of structural variants (SVs), and previous studies have indicated that OGM could serve as a generic cytogenetic tool for hematological malignancies. Herein, we report the results from our study evaluating the concordance of OGM and standard-of-care FISH in 18 CLL samples. The results were fully concordant between these two techniques in the blinded comparison. Using in silico dilution series, the lowest limit of detection with OGM was determined to range between 3 and 9% variant allele fractions. Genome-wide analysis by OGM revealed additional (>1 Mb) aberrations in 78% of the samples, including both unbalanced and balanced SVs. Importantly, OGM also enabled the detection of clinically relevant complex karyotypes, undetectable by FISH, in three samples. Overall, this study demonstrates the potential of OGM as a first-tier cytogenetic test for CLL and as a powerful tool for genome-wide SV analysis.

Abstract: It has been well-established that mutations in BRCA1 and BRCA2, compromising functions in DNA double-strand break repair (DSBR), confer hereditary breast and ovarian cancer risk. Importantly, mutations in these genes explain only a minor fraction of the hereditary risk and of the subset of DSBR deficient tumors. Our screening efforts identified two truncating germline mutations in the gene encoding the BRCA1 complex partner ABRAXAS1 in German early-onset breast cancer patients. To unravel the molecular mechanisms triggering carcinogenesis in these carriers of heterozygous mutations, we examined DSBR functions in patient-derived lymphoblastoid cells (LCLs) and in genetically manipulated mammary epithelial cells. By use of these strategies we were able to demonstrate that these truncating ABRAXAS1 mutations exerted dominant effects on BRCA1 functions. Interestingly, we did not observe haploinsufficiency regarding homologous recombination (HR) proficiency (reporter assay, RAD51-foci, PARP-inhibitor sensitivity) in mutation carriers. However, the balance was shifted to use of mutagenic DSBR-pathways. The dominant effect of truncated ABRAXAS1 devoid of the C-terminal BRCA1 binding site can be explained by retention of the N-terminal interaction sites for other BRCA1-A complex partners like RAP80. In this case BRCA1 was channeled from the BRCA1-A to the BRCA1-C complex, which induced single-strand annealing (SSA). Further truncation, additionally deleting the coiled-coil region of ABRAXAS1, unleashed excessive DNA damage responses (DDRs) de-repressing multiple DSBR-pathways including SSA and non-homologous end-joining (NHEJ). Our data reveal de-repression of low-fidelity repair activities as a common feature of cells from patients with heterozygous mutations in genes encoding BRCA1 and its complex partners.

Abstract: Copy number variants (CNVs) are a major source of genetic variation and can disrupt genes or affect gene dosage. They are known to be causal or underlie predisposition to various diseases. However, the role of CNVs in inherited breast cancer susceptibility has not been thoroughly investigated. To address this, we performed whole-exome sequencing based analysis of rare CNVs in 98 high-risk Northern Finnish breast cancer cases. After filtering, selected candidate alleles were validated and characterized with a combination of orthogonal methods, including PCR-based approaches, optical genome mapping and long-read sequencing. This revealed three recurrent alterations: a 31 kb deletion co-occurring with a retrotransposon insertion (delins) in RAD52, a 13.4 kb deletion in HSD17B14 and a 64 kb partial duplication of RAD51C. Notably, all these genes encode proteins involved in pathways previously identified as essential for breast cancer development. Variants were genotyped in geographically matched cases and controls (altogether 278 hereditary and 1983 unselected breast cancer cases, and 1229 controls). The RAD52 delins and HSD17B14 deletion both showed significant enrichment among cases with indications of hereditary disease susceptibility. RAD52 delins was identified in 7/278 cases (2.5%, P = 0.034, OR = 2.86, 95% CI = 1.10–7.45) and HSD17B14 deletion in 8/278 cases (2.9%, P = 0.014, OR = 3.28, 95% CI = 1.31–8.23), the frequency of both variants in the controls being 11/1229 (0.9%). This suggests a role for RAD52 and HSD17B14 in hereditary breast cancer susceptibility. The RAD51C duplication was very rare, identified only in 2/278 of hereditary cases and 2/1229 controls (P = 0.157, OR = 4.45, 95% CI = 0.62–31.70). The identification of recurrent CNVs in these genes, and especially the relatively high frequency of RAD52 and HSD17B14 alterations in the Finnish population, highlights the importance of studying CNVs alongside single nucleotide variants when searchin

Abstract: ATM is generally described as a moderate-risk breast cancer susceptibility gene. However, some of ATM variants might encounter higher risk. ATM c.7570G>C, p.Ala2524Pro, (rs769142993) is a pathogenic Finnish founder variant causative for recessively inherited ataxia-telangiectasia. At cellular level, it has been reported to have a dominant-negative effect. ATM c.7570G>C has recurrently been described in Finnish breast cancer families and unselected case cohorts collected from different parts of the country, but the rarity of the allele (MAF 0.0002772 in Finns) and lack of confirming segregation analyses have prevented any conclusive risk estimates. Here, we describe seven families from genetic counseling units with ATM c.7570G>C variant showing co-segregation with breast cancer. Further analysis of the unselected breast cancer cohort from Northern Finland (n = 1822), a geographical region previously indicated to have enrichment of the variant, demonstrated that c.7570G>C significantly associates with breast cancer, and the risk is estimated as high (odds ratio [OR] = 8.5, 95% confidence interval [CI] = 1.04-62.46, P = .018). Altogether, these results place ATM c.7570G>C variant among the high-risk alleles for breast cancer, which should be taken into consideration in genetic counseling.

Abstract: Biallelic loss-of-function variants in the SMG9 gene, encoding a regulatory subunit of the mRNA nonsense-mediated decay (NMD) machinery, are reported to cause heart and brain malformation syndrome. Here we report five patients from three unrelated families with intellectual disability (ID) and a novel pathogenic SMG9 c.551 T > C p.(Val184Ala) homozygous missense variant, identified using exome sequencing. Sanger sequencing confirmed recessive segregation in each family. SMG9 c.551T > C p.(Val184Ala) is most likely an autozygous variant identical by descent. Characteristic clinical findings in patients were mild to moderate ID, intention tremor, pyramidal signs, dyspraxia, and ocular manifestations. We used RNA sequencing of patients and age- and sex-matched healthy controls to assess the effect of the variant. RNA sequencing revealed that the SMG9 c.551T > C variant did not affect the splicing or expression level of SMG9 gene products, and allele-specific expression analysis did not provide evidence that the nonsense mRNA-induced NMD was affected. Differential gene expression analysis identified prevalent upregulation of genes in patients, including the genes SMOX, OSBP2, GPX3, and ZNF155. These findings suggest that normal SMG9 function may be involved in transcriptional regulation without affecting nonsense mRNA-induced NMD. In conclusion, we demonstrate that the SMG9 c.551T > C missense variant causes a neurodevelopmental disorder and impacts gene expression. NMD components have roles beyond aberrant mRNA degradation that are crucial for neurocognitive development.

Abstract: Objective: Cardiac hypertrophy with varying degrees of myocardial fibrosis is commonly associated with coronary artery disease (CAD) related sudden cardiac death (SCD), especially in young victims among whom patterns of coronary artery lesions do not entirely appear to explain the cause of SCD. Our aim was to study the genetic background of hypertrophy, with or without fibrosis, among ischemic SCD victims with single vessel CAD. Methods: The study population was derived from the Fingesture study, consisting of all autopsy-verified SCDs in Northern Finland between the years 1998 and 2017 (n = 5,869). We carried out targeted next-generation sequencing using a panel of 174 genes associated with myocardial structure and ion channel function in 95 ischemic-SCD victims (mean age 63.6 ± 10.3 years; 88.4% males) with single-vessel CAD in the absence of previously diagnosed CAD and cardiac hypertrophy with or without myocardial fibrosis at autopsy. Results: A total of 42 rare variants were detected in 43 subjects (45.3% of the study subjects). Five variants in eight subjects (8.4%) were classified as pathogenic or likely pathogenic. We observed 37 variants of uncertain significance in 39 subjects (40.6%). Variants were detected in myocardial structure protein coding genes, associated with arrhythmogenic right ventricular, dilated, hypertrophic and left ventricular non-compaction cardiomyopathies. Also, variants were detected in ryanodine receptor 2 (RYR2), a gene associated with both cardiomyopathies and catecholaminergic polymorphic ventricular tachycardias. Conclusions: Rare variants associated with cardiomyopathies, in the absence of anatomic evidence of the specific inherited cardiomyopathies, were common findings among CAD-related SCD victims with single vessel disease and myocardial hypertrophy found at autopsies, suggesting that these variants may modulate the risk for fatal arrhythmias and SCD in ischemic disease.

Abstract: Autosomal genetic analyses of blood lipids have yielded key insights for coronary heart disease (CHD). However, X chromosome genetic variation is understudied for blood lipids in large sample sizes. We now analyze genetic and blood lipid data in a high-coverage whole X chromosome sequencing study of 65,322 multi-ancestry participants and perform replication among 456,893 European participants. Common alleles on chromosome Xq23 are strongly associated with reduced total cholesterol, LDL cholesterol, and triglycerides (min P = 8.5 × 10−72), with similar effects for males and females. Chromosome Xq23 lipid-lowering alleles are associated with reduced odds for CHD among 42,545 cases and 591,247 controls (P = 1.7 × 10−4), and reduced odds for diabetes mellitus type 2 among 54,095 cases and 573,885 controls (P = 1.4 × 10−5). Although we observe an association with increased BMI, waist-to-hip ratio adjusted for BMI is reduced, bioimpedance analyses indicate increased gluteofemoral fat, and abdominal MRI analyses indicate reduced visceral adiposity. Co-localization analyses strongly correlate increased CHRDL1 gene expression, particularly in adipose tissue, with reduced concentrations of blood lipids.

Abstract: A combination of genetic and functional approaches has identified three independent breast cancer risk loci at 2q35. A recent fine-scale mapping analysis to refine these associations resulted in 1 (signal 1), 5 (signal 2), and 42 (signal 3) credible causal variants at these loci. We used publicly available in silico DNase I and ChIP-seq data with in vitro reporter gene and CRISPR assays to annotate signals 2 and 3. We identified putative regulatory elements that enhanced cell-type-specific transcription from the IGFBP5 promoter at both signals (30- to 40-fold increased expression by the putative regulatory element at signal 2, 2- to 3-fold by the putative regulatory element at signal 3). We further identified one of the five credible causal variants at signal 2, a 1.4 kb deletion (esv3594306), as the likely causal variant; the deletion allele of this variant was associated with an average additional increase in IGFBP5 expression of 1.3-fold (MCF-7) and 2.2-fold (T-47D). We propose a model in which the deletion allele of esv3594306 juxtaposes two transcription factor binding regions (annotated by estrogen receptor alpha ChIP-seq peaks) to generate a single extended regulatory element. This regulatory element increases cell-type-specific expression of the tumor suppressor gene IGFBP5 and, thereby, reduces risk of estrogen receptor-positive breast cancer (odds ratio = 0.77, 95% CI 0.74–0.81, p = 3.1 × 10−31).

Abstract: The contribution of genetic variants to non-ischemic sudden cardiac death (SCD) due to acquired myocardial diseases is unclear. We studied whether SCD victims with hypertension/obesity related hypertrophic myocardial disease harbor potentially disease associated gene variants. The Fingesture study has collected data from 5869 autopsy-verified SCD victims in Northern Finland. Among SCD victims, 740 (13%) had hypertension and/or obesity as the most likely explanation for myocardial disease with hypertrophy and fibrosis. We performed next generation sequencing using a panel of 174 cardiac genes for 151 such victims with the best quality of DNA. We used 48 patients with hypertension and hypertrophic heart as controls. Likely pathogenic variants were identified in 15 SCD victims (10%) and variants of uncertain significance (VUS) were observed in additional 43 SCD victims (28%). In controls, likely pathogenic variants were present in two subjects (4%; p = 0.21) and VUSs in 12 subjects (25%; p = 0.64). Among SCD victims, presence of potentially disease-related variants was associated with lower mean BMI and heart weight. Potentially disease related gene variants are common in non-ischemic SCD but further studies are required to determine specific contribution of rare genetic variants to the extent of acquired myocardial diseases leading to SCD.

Abstract: Background: Breast cancer is strongly influenced by hereditary risk factors. Yet, the known susceptibility genes and genomic loci explain only about half of the familial component of the disease. To identify novel breast cancer predisposing gene defects, here we have performed massive parallel sequencing for Northern Finnish breast cancer cases. Methods: Ninety-eight breast cancer cases with indication of hereditary disease susceptibility were exome sequenced. Data filtering strategy focused on predictably deleterious rare variants that were still enriched in the sequenced cohort. Findings were confirmed with additional, geographically matched breast cancer cohorts. Results: A recurrent heterozygous splice acceptor variant, c.918-1G>C, in SERPINA3, was identified, and it was significantly enriched both in the hereditary (6/201, 3.0%, p = 0.006, OR 5.1, 95% CI 1.7–14.8) and unselected breast cancer cohort (26/1569, 1.7%, p = 0.009, OR 2.8, 95% CI 1.3–6.2). SERPINA3 c.918-1G>C carriers were also significantly more likely to have a rare tumor subtype, medullary breast cancer, than the non-carriers (4/26, 15.4%, p = 0.000014, OR 42.9, 95% CI 11.7–157.1). Conclusion: These findings demonstrate that c.918-1G>C germline variant in SERPINA3 gene, encoding a member of the serine protease inhibitor class, is a novel breast cancer predisposing allele.

Abstract: Background: Epidemiological studies provide strong evidence for a role of endogenous sex hormones in the aetiology of breast cancer. The aim of this analysis was to identify genetic variants that are associated with urinary sex-hormone levels and breast cancer risk. Methods: We carried out a genome-wide association study of urinary oestrone-3-glucuronide and pregnanediol-3-glucuronide levels in 560 premenopausal women, with additional analysis of progesterone levels in 298 premenopausal women. To test for the association with breast cancer risk, we carried out follow-up genotyping in 90,916 cases and 89,893 controls from the Breast Cancer Association Consortium. All women were of European ancestry. Results: For pregnanediol-3-glucuronide, there were no genome-wide significant associations; for oestrone-3-glucuronide, we identified a single peak mapping to the CYP3A locus, annotated by rs45446698. The minor rs45446698-C allele was associated with lower oestrone-3-glucuronide (−49.2%, 95% CI −56.1% to −41.1%, P = 3.1 × 10⁻¹⁸); in follow-up analyses, rs45446698-C was also associated with lower progesterone (−26.7%, 95% CI −39.4% to −11.6%, P = 0.001) and reduced risk of oestrogen and progesterone receptor-positive breast cancer (OR = 0.86, 95% CI 0.82–0.91, P = 6.9 × 10⁻¹⁸). Conclusions: The CYP3A7*1C allele is associated with reduced risk of hormone receptor-positive breast cancer possibly mediated via an effect on the metabolism of endogenous sex hormones in premenopausal women.

Abstract: Previous transcriptome-wide association studies (TWAS) have identified breast cancer risk genes by integrating data from expression quantitative loci and genome-wide association studies (GWAS), but analyses of breast cancer subtype-specific associations have been limited. In this study, we conducted a TWAS using gene expression data from GTEx and summary statistics from the hitherto largest GWAS meta-analysis conducted for breast cancer overall, and by estrogen receptor subtypes (ER+ and ER−). We further compared associations with ER+ and ER− subtypes, using a case-only TWAS approach. We also conducted multigene conditional analyses in regions with multiple TWAS associations. Two genes, STXBP4 and HIST2H2BA, were specifically associated with ER+ but not with ER– breast cancer. We further identified 30 TWAS-significant genes associated with overall breast cancer risk, including four that were not identified in previous studies. Conditional analyses identified single independent breast-cancer gene in three of six regions harboring multiple TWAS-significant genes. Our study provides new information on breast cancer genetics and biology, particularly about genomic differences between ER+ and ER− breast cancer.

Abstract: Background: Rare protein truncating variants of NTHL1 gene are causative for the recently described, recessively inherited NTHL1 tumor syndrome that is characterized by an increased lifetime risk for colorectal cancer, colorectal polyposis, and breast cancer. Although there is strong evidence for breast cancer being a part of the cancer spectrum in these families, the role of pathogenic NTHL1 variants in breast cancer susceptibility in general population remains unclear. Methods: We tested the prevalence of NTHL1 nonsense variant c.268C>T, p.Q90*, which is the major allele in NTHL1 families and also shows enrichment in the Finnish population, in a total of 1333 breast cancer patients. Genotyping was performed for DNA samples extracted from peripheral blood by using high‐resolution melt analysis. Results: Sixteen NTHL1 p.Q90* heterozygous carriers were identified (1.2%, p = 0.61): 5 in hereditary cohort (n = 234, 2.1%, p = 0.39) and 11 in unselected cohort (n = 1099, 1.0%, p = 0.36). This frequency is equal to that in the general population (19/1324, 1.4%). No NTHL1 p.Q90* homozygotes were identified. Conclusion: Our results indicate that NTHL1 p.Q90* heterozygous carriers do not have an increased risk for breast cancer and that the variant is unlikely to be a significant contributor to breast cancer risk at the population level.

Abstract: Purpose: Next-generation sequencing (NGS) has made genetic testing of patients with epileptic encephalopathies easier — novel variants are discovered and new phenotypes described. Variants in the same gene — even the same variant — can cause different types of epilepsy and neurodevelopmental disorders. Our aim was to identify the genetic causes of epileptic encephalopathies in paediatric patients with complex phenotypes. Methods: NGS was carried out for three patients with epileptic encephalopathies. Detailed clinical features, brain magnetic resonance imaging and electroencephalography were analysed. We searched the Human Gene Mutation Database for the published GABRG2 variants with clinical description of patients and composed a summary of the variants and their phenotypic features. Results: We identified two novel de novo GABRG2 variants, p.P282T and p.S306F, with new phenotypes including neuroradiological evidence of neurodegeneration and epilepsy of infancy with migrating focal seizures (EIMFS). One patient carried previously reported p.P83S variant with autism spectrum disorder (ASD) phenotype that has not yet been described related to GABRG2 disorders and a more severe epilepsy phenotype than reported earlier. In all, the literature search yielded twenty-two articles describing 27 different variants that were divided into two categories: those with self-limiting epilepsies and febrile seizures and those with more severe drug-resistant epileptic encephalopathies. Conclusion: This study further expands the genotypic and phenotypic spectrum of epilepsies associated with GABRG2 variants. More knowledge is still needed about the influence of the environment, genetic background and other epilepsy susceptibility genes on the phenotype of the specific GABRG2 variants.

Abstract: Whilst heterozygous germline mutations in the ABRAXAS1 gene have been associated with a hereditary predisposition to breast cancer, their effect on promoting tumourigenesis at the cellular level has not been explored. Here, we demonstrate in patient-derived cells that the Finnish ABRAXAS1 founder mutation (c.1082G > A, Arg361Gln), even in the heterozygous state leads to decreased BRCA1 protein levels as well as reduced nuclear localization and foci formation of BRCA1 and CtIP. This causes disturbances in basal BRCA1-A complex localization, which is reflected by a restraint in error-prone DNA double-strand break repair pathway usage, attenuated DNA damage response and deregulated G2-M checkpoint control. The current study clearly demonstrates how the Finnish ABRAXAS1 founder mutation acts in a dominant-negative manner on BRCA1 to promote genome destabilization in heterozygous carrier cells.

Abstract: Strong inherited predisposition to breast cancer is estimated to cause about 5–10% of all breast cancer cases. As the known susceptibility genes, such as BRCA1 and BRCA2, explain only a fraction of this, additional predisposing genes and related biological mechanisms are actively being searched for. We have recently identified a recurrent MCPH1 germline mutation, p.Arg304ValfsTer3, as a breast cancer susceptibility allele. MCPH1 encodes a multifunctional protein involved in maintenance of genomic integrity and it is also somatically altered in various cancer types, including breast cancer. Additionally, biallelic MCPH1 mutations are causative for microcephaly and at cellular level premature chromosome condensation. To study the molecular mechanisms leading to cancer predisposition and malignant conversion, here we have modeled the effect of MCPH1 p.Arg304ValfsTer3 mutation using gene‐edited MCF10A breast epithelial cells. As a complementary approach, we also sought for additional potential cancer driver mutations in MCPH1 p.Arg304ValfsTer3 carrier breast tumors. We show that mutated MCPH1 de‐regulates transcriptional programs related to invasion and metastasis and leads to downregulation of histone genes. These global transcriptional changes are mirrored by significantly increased migration and invasion potential of the cells as well as abnormal chromosomal condensation both before and after mitosis. These findings provide novel molecular insights to MCPH1 tumor suppressor functions and establish a role in regulation of transcriptional programs related to malignant conversion and chromosomal assembly. The MCPH1 p.Arg304ValfsTer3 carrier breast tumors showed recurrent tumor suppressor gene TP53 mutations, which were also significantly over‐represented in breast tumors with somatically inactivated MCPH1.

Abstract: Stratification of women according to their risk of breast cancer based on polygenic risk scores (PRSs) could improve screening and prevention strategies. Our aim was to develop PRSs, optimized for prediction of estrogen receptor (ER)-specific disease, from the largest available genome-wide association dataset and to empirically validate the PRSs in prospective studies. The development dataset comprised 94,075 case subjects and 75,017 control subjects of European ancestry from 69 studies, divided into training and validation sets. Samples were genotyped using genome-wide arrays, and single-nucleotide polymorphisms (SNPs) were selected by stepwise regression or lasso penalized regression. The best performing PRSs were validated in an independent test set comprising 11,428 case subjects and 18,323 control subjects from 10 prospective studies and 190,040 women from UK Biobank (3,215 incident breast cancers). For the best PRSs (313 SNPs), the odds ratio for overall disease per 1 standard deviation in ten prospective studies was 1.61 (95%CI: 1.57–1.65) with area under receiver-operator curve (AUC) = 0.630 (95%CI: 0.628–0.651). The lifetime risk of overall breast cancer in the top centile of the PRSs was 32.6%. Compared with women in the middle quintile, those in the highest 1% of risk had 4.37- and 2.78-fold risks, and those in the lowest 1% of risk had 0.16- and 0.27-fold risks, of developing ER-positive and ER-negative disease, respectively. Goodness-of-fit tests indicated that this PRS was well calibrated and predicts disease risk accurately in the tails of the distribution. This PRS is a powerful and reliable predictor of breast cancer risk that may improve breast cancer prevention programs.

Abstract: Although the spliceogenic nature of the BRCA2 c.68-7T > A variant has been demonstrated, its association with cancer risk remains controversial. In this study, we accurately quantified by real-time PCR and digital PCR (dPCR), the BRCA2 isoforms retaining or missing exon 3. In addition, the combined odds ratio for causality of the variant was estimated using genetic and clinical data, and its associated cancer risk was estimated by case-control analysis in 83,636 individuals. Co-occurrence in trans with pathogenic BRCA2 variants was assessed in 5,382 families. Exon 3 exclusion rate was 4.5-fold higher in variant carriers (13%) than controls (3%), indicating an exclusion rate for the c.68-7T > A allele of approximately 20%. The posterior probability of pathogenicity was 7.44 × 10-115. There was neither evidence for increased risk of breast cancer (OR 1.03; 95% CI 0.86-1.24) nor for a deleterious effect of the variant when co-occurring with pathogenic variants. Our data provide for the first time robust evidence of the nonpathogenicity of the BRCA2 c.68-7T > A. Genetic and quantitative transcript analyses together inform the threshold for the ratio between functional and altered BRCA2 isoforms compatible with normal cell function. These findings might be exploited to assess the relevance for cancer risk of other BRCA2 spliceogenic variants.

Abstract: Several known breast cancer susceptibility genes with moderate‐to‐high risk alleles encode proteins involved in DNA damage response (DDR). As these explain less than half of the hereditary breast cancer cases, additional predisposing alleles are likely to be discovered. Many of the previous studies utilizing massive parallel sequencing have focused on the protein‐truncating variants, and the role of rare missense mutations has remained poorly addressed. To identify novel susceptibility factors, we have systematically analyzed the data from our parallel sequencing of 796 DDR genes in 189 Northern Finnish hereditary breast cancer patients for rare missense variants, predicted as deleterious. Thirty‐five variants were studied here for the disease association using Finnish breast cancer case (n = 492–2,035) and control (n = 277–1,539) cohorts. As a result, two missense variants in genes involved in DNA replication, RECQL p.I156M and POLG p.L392V, the former involving genomic and the latter mitochondrial DNA replication, showed significant association with risk of breast cancer. Rare RECQL p.I156M allele was observed in breast cancer cases only (6/1,946, 0.3%, p = 0.043), whereas POLG p.L392V was two times more frequent in breast cancer cases (53/2,238, 2.4%) compared to controls (18/1,539, 1.2%, OR = 2.1, 95% CI 1.2–3.5, p = 0.010). Based on the current genetic data, both RECQL p.I156M and POLG p.L392V represent novel breast cancer predisposing alleles.

24. Machine learning identifies interacting genetic variants contributing to breast cancer risk:a case study in Finnish cases and controls

Abstract: We propose an effective machine learning approach to identify group of interacting single nucleotide polymorphisms (SNPs), which contribute most to the breast cancer (BC) risk by assuming dependencies among BCAC iCOGS SNPs. We adopt a gradient tree boosting method followed by an adaptive iterative SNP search to capture complex non-linear SNP-SNP interactions and consequently, obtain group of interacting SNPs with high BC risk-predictive potential. We also propose a support vector machine formed by the identified SNPs to classify BC cases and controls. Our approach achieves mean average precision (mAP) of 72.66, 67.24 and 69.25 in discriminating BC cases and controls in KBCP, OBCS and merged KBCP-OBCS sample sets, respectively. These results are better than the mAP of 70.08, 63.61 and 66.41 obtained by using a polygenic risk score model derived from 51 known BC-associated SNPs, respectively, in KBCP, OBCS and merged KBCP-OBCS sample sets. BC subtype analysis further reveals that the 200 identified KBCP SNPs from the proposed method performs favorably in classifying estrogen receptor positive (ER+) and negative (ER−) BC cases both in KBCP and OBCS data. Further, a biological analysis of the identified SNPs reveals genes related to important BC-related mechanisms, estrogen metabolism and apoptosis.

Abstract: The breast cancer risk variants identified in genome-wide association studies explain only a small fraction of the familial relative risk, and the genes responsible for these associations remain largely unknown. To identify novel risk loci and likely causal genes, we performed a transcriptome-wide association study evaluating associations of genetically predicted gene expression with breast cancer risk in 122,977 cases and 105,974 controls of European ancestry. We used data from the Genotype-Tissue Expression Project to establish genetic models to predict gene expression in breast tissue and evaluated model performance using data from The Cancer Genome Atlas. Of the 8,597 genes evaluated, significant associations were identified for 48 at a Bonferroni-corrected threshold of P < 5.82 × 10−6, including 14 genes at loci not yet reported for breast cancer. We silenced 13 genes and showed an effect for 11 on cell proliferation and/or colony-forming efficiency. Our study provides new insights into breast cancer genetics and biology.

Abstract: Although the spliceogenic nature of the BRCA2 c.68‐7T > A variant has been demonstrated, its association with cancer risk remains controversial. In this study, we accurately quantified by real‐time PCR and digital PCR (dPCR), the BRCA2 isoforms retaining or missing exon 3. In addition, the combined odds ratio for causality of the variant was estimated using genetic and clinical data, and its associated cancer risk was estimated by case‐control analysis in 83,636 individuals. Co‐occurrence in trans with pathogenic BRCA2 variants was assessed in 5,382 families. Exon 3 exclusion rate was 4.5‐fold higher in variant carriers (13%) than controls (3%), indicating an exclusion rate for the c.68‐7T > A allele of approximately 20%. The posterior probability of pathogenicity was 7.44 × 10⁻¹¹⁵. There was neither evidence for increased risk of breast cancer (OR 1.03; 95% CI 0.86–1.24) nor for a deleterious effect of the variant when co‐occurring with pathogenic variants. Our data provide for the first time robust evidence of the nonpathogenicity of the BRCA2 c.68‐7T > A. Genetic and quantitative transcript analyses together inform the threshold for the ratio between functional and altered BRCA2 isoforms compatible with normal cell function. These findings might be exploited to assess the relevance for cancer risk of other BRCA2 spliceogenic variants.

27. Hereditary predisposition to breast cancer:evaluating the role of rare copy number variant, protein-truncating and missense candidate alleles

Author: Pylkäs, K. (Katri), Winqvist, R. (Robert), Tervasmäki, A. (Anna), Pylkäs, K. (Katri), Winqvist, R. (Robert), and Tervasmäki, A. (Anna)
Abstract: Breast cancer is the most common cancer among women, and inherited predisposition is one of the major recognized causes of increased breast cancer risk. Only about half of the hereditary cases are explained by mutations in the known susceptibility genes, including the DNA damage response genes BRCA1, BRCA2 and PALB2, leaving the majority still uncovered. Identification of the missing genetic predisposing factors is important for more effective diagnostics and counseling of the risk families, and also for better understanding of the etiology and cellular characteristics of breast cancer. The first aim of this study was to investigate the cancer associations of six rare germline copy number variant (CNV) deletions, which were previously identified in breast cancer patients by a genome-wide microarray approach. The second aim was to identify novel susceptibility alleles, both protein-truncating variants and missense mutations, by next-generation sequencing (NGS) of nearly 800 DNA damage response genes in 189 hereditary breast cancer patients. The cancer-associations of all selected candidate alleles (6 CNVs, 39 protein-truncating variants and 35 missense mutations) were studied by case-control approach using DNA samples from several hundred breast cancer patients and healthy controls. The prevalence of the studied CNVs did not significantly differ between the cases and controls, but when studying the associations with specific clinical parameters, deletion in the CYP2C19 gene showed enrichment in the breast cancer patients with hormonally triple-negative tumors (p=0.021). As CYP2C19 functions in estrogen metabolism, the results indicate that disturbance of hormonal balance due to enzyme defects may predispose specifically to the estrogen receptor-negative subtype of breast cancer. Two protein truncating-variants, TEX15 c.7253dupT and FANCD2 c.2715+1G>A showed significant breast cancer association in the Northern Finnish cohort (p=0.018 and p=0.036, respecti, Tiivistelmä Rintasyöpä on naisten yleisin syöpä, ja perinnöllinen alttius on yksi merkittävimmistä sairastumisriskiin vaikuttavista tekijöistä.

Abstract: Breast cancer is the most common malignancy in women and it is strongly influenced by hereditary risk factors. So far, most of the breast cancer-associated genes, including BRCA1/2, have been identified among those that encode proteins involved in DNA damage response (DDR) pathways. However, known genetic risk factors explain less than half of the familial risk of breast cancer. Identification of novel genes and mutations that predispose to breast cancer is important for the understanding of the mechanisms that contribute to the disease development and also for the identification of those individuals who are at high risk. The first aim of this study was to resolve the complementation groups of Finnish patients with Fanconi anemia (FA), which is a rare genetic disease caused by defects in a specific DDR pathway, and to study the role of the causative gene mutations in breast cancer predisposition. The second aim of this study was to identify novel breast cancer susceptibility genes and alleles by targeted next-generation sequencing (NGS) of multiple (~800) DDR related genes. In both approaches, the identified gene mutations were subjected to case-control association analysis utilizing DNA samples of over 1,000 breast cancer cases and 1,000 healthy controls. Investigation of the Finnish FA patients revealed six different disease-causing mutations in three different genes (FANCA, FANCG and FANCI). All of the studied mutations were recurrent in the Finnish population but did not associate with breast cancer. Targeted NGS identified three novel potential breast cancer susceptibility genes. A significant enrichment of TEX15 c.7253dupT and FANCD2 c.2715+1G>A mutations was observed among the hereditary breast cancer cases (P = 0.018 and P = 0.036, respectively). The strongest evidence was found for a Finnish founder mutation in MCPH1 (c.904_916del), which associated with breast cancer susceptibility both in familial (P = 0.003, OR 8.3) and unselected (P = 0.016, Tiivistelmä Rintasyöpä on naisten yleisin syöpä.

Abstract: Purpose: The FANCM c.5101C>T nonsense mutation was previously found to associate with breast cancer in the Finnish population, especially among triple-negative cases. Here, we studied the prevalence of three other FANCM variants: c.5791C>T, which has been reported to predispose to familial breast cancer, and the c.4025_4026delCT and c.5293dupA variants recently identified in Finnish cancer patients. Methods: We genotyped the FANCM c.5791C>mutation in 4806 invasive breast cancer patients, including BRCA1/2 mutation negative familial cases and unselected cases, and in 2734 healthy population controls from four different geographical areas of Finland. The association of the mutation with breast cancer risk among patient subgroups was statistically evaluated. We further analyzed the combined risk associated with c.5101C>T and c.5791C>T mutations. We also genotyped 526 unselected ovarian cancer patients for the c.5791C>T mutation and 862 familial breast cancer patients for the c.4025_4026delCT and c.5293dupA variants. Results: The frequency of the FANCM c.5791C>T mutation was higher among breast cancer cases than in controls (OR 1.94, 95% CI 0.87–4.32, P = 0.11), with a statistically significant association with triple-negative breast cancer (OR 5.14, 95% CI 1.65–16.0, P = 0.005). The combined analysis for c.5101C>T and c.5791C>T carriers confirmed a strong association with breast cancer (OR 1.86, 95% CI 1.32–2.49, P = 0.0002), especially among the triple-negative patients (OR 3.08, 95% CI 1.77–5.35, P = 0.00007). For the other variants, only one additional c.4025_4026delCT carrier and no c.5293dupA carriers were observed. Conclusions: These results support the role of FANCM as a breast cancer susceptibility gene, particularly for triple-negative breast cancer.

Abstract: Background: The rarity of mutations in PALB2, CHEK2 and ATM make it difficult to estimate precisely associated cancer risks. Population-based family studies have provided evidence that at least some of these mutations are associated with breast cancer risk as high as those associated with rare BRCA2 mutations. We aimed to estimate the relative risks associated with specific rare variants in PALB2, CHEK2 and ATM via a multicentre case-control study. Methods: We genotyped 10 rare mutations using the custom iCOGS array: PALB2 c.1592delT, c.2816T>G and c.3113G>A, CHEK2 c.349A>G, c.538C>T, c.715G>A, c.1036C>T, c.1312G>T, and c.1343T>G and ATM c.7271T>G. We assessed associations with breast cancer risk (42 671 cases and 42 164 controls), as well as prostate (22 301 cases and 22 320 controls) and ovarian (14 542 cases and 23 491 controls) cancer risk, for each variant. Results: For European women, strong evidence of association with breast cancer risk was observed for PALB2 c.1592delT OR 3.44 (95% CI 1.39 to 8.52, p = 7.1 × 10⁻⁵), PALB2 c.3113G>A OR 4.21 (95% CI 1.84 to 9.60, p = 6.9 × 10⁻⁸) and ATM c.7271T>G OR 11.0 (95% CI 1.42 to 85.7, p = 0.0012). We also found evidence of association with breast cancer risk for three variants in CHEK2, c.349A>G OR 2.26 (95% CI 1.29 to 3.95), c.1036C>T OR 5.06 (95% CI 1.09 to 23.5) and c.538C>T OR 1.33 (95% CI 1.05 to 1.67) (p ≤ 0.017). Evidence for prostate cancer risk was observed for CHEK2 c.1343T>G OR 3.03 (95% CI 1.53 to 6.03, p = 0.0006) for African men and CHEK2 c.1312G>T OR 2.21 (95% CI 1.06 to 4.63, p = 0.030) for European men. No evidence of association with ovarian cancer was found for any of these variants. Conclusions: This report adds to accumulating evidence that at least some variants in these genes are associated with an increased risk of breast cancer that is clinically important.

31. Hereditary predisposition to breast cancer – with a focus on AATF, MRG15, PALB2, and three Fanconi anaemia genes

Abstract: Around 5−10% of all breast cancer cases are estimated to result from a strong hereditary predisposition to the disease. However, mutations in the currently known breast cancer susceptibility genes account for only 20−30% of all familial cases. Additional factors contributing to the pathogenesis of breast cancer, therefore, await discovery. Aims of this study were to evaluate variations of the AATF and MRG15 genes as novel potential candidates for breast cancer susceptibility, to further examine the prevalence of the cancer-related PALB2 c.1592delT mutation among BRCA-negative high-risk breast cancer families counselled at the Department of Clinical Genetics, Oulu University Hospital, to identify Finnish Fanconi anaemia patients complementation groups as well as causative mutations, and to evaluate the potential role of these mutations in breast cancer susceptibility. The analysis of 121 familial breast cancer cases revealed altogether seven different sequence changes in the AATF gene. However, none of them were considered pathogenic, suggesting that germline mutations in AATF are rare or absent in breast cancer patients. Investigation of the MRG15 gene among familial breast cancer cases revealed seven previously unreported variants, but in silico analyses revealed that none of these variants appeared to modify the function of MRG15. The results suggest that MRG15 alterations are unlikely to be significant breast cancer susceptibility alleles. A previously identified pathogenic PALB2 mutation, c.1592delT, was identified in three patients from a cohort of 62 high-risk BRCA1/2-negative breast cancer patients from the Department of Clinical Genetics. PALB2 c.1592delT mutation testing should thus be a routine part of the genetic counselling protocol, particularly for BRCA1/2-negative high-risk breast cancer patients. Investigation of the complementation groups of Finnish Fanconi anaemia patients revealed a total of six different causative mutations.

32. Role of the RNF8, UBC13, MMS2 and RAD51C DNA damage response genes and rare copy number variants in hereditary predisposition to breast cancer

Abstract: Mutations in the currently known breast cancer susceptibility genes account for only 25–30% of all familial cases. Novel susceptibility genes can be identified by several methods, including candidate gene re-sequencing and genome-wide microarrays. We have applied microarrays for the detection of a new genomic variation class, copy number variants (CNVs), which potentially could disrupt genes in multiple pathways related to breast cancer susceptibility. The aim of the current study was to evaluate the role of the RNF8, UBC13, MMS2 and RAD51C DNA damage response genes in breast cancer susceptibility as well as to study if rare CNVs are associated with the predisposition to this disease. The analysis of 123 familial breast cancer cases revealed altogether nine different changes in the RNF8 and UBC13 candidate genes. However, none of the observed alterations were considered pathogenic. No alterations were observed in MMS2. The obtained results suggest that breast cancer predisposing alterations in RNF8, UBC13 and MMS2 are rare, or even absent. The RAD51C mutation screening of 147 familial breast cancer cases and 232 unselected ovarian cancer cases revealed two deleterious mutations: c.-13_14del27 was observed in a breast cancer case with familial history of ovarian cancer and c.774delT in an ovarian cancer case. Both mutations were absent in the control cohort. The results of the study support the hypothesis that rare variants of RAD51C predispose predominantly to ovarian cancer. A genome-wide scan of CNVs was performed for 103 familial breast cancer cases and 128 controls. The biological networks of the genes disrupted by CNVs were different between the two groups. In familial breast cancer cases, the observed mutations disrupted genes, which were significantly overrepresented in cellular functions related to maintenance of genomic integrity (P=0.0211). Biological network analysis showed that the disrupted genes were closely related to estrogen signaling and T, Tiivistelmä Tunnetut rintasyöpäalttiusgeenien mutaatiot selittävät vain 25–30 prosenttia kaikista perinnöllisistä rintasyöpätapauksista.

33. BRCA/Fanconi anemia pathway genes in hereditary predisposition to breast cancer

Abstract: Two major genes are involved in hereditary predisposition to breast and ovarian cancer — BRCA1 and BRCA2. However, germline mutations in these tumor suppressors account for a maximum 20% of the familial breast cancer cases. A significant portion of the genes predisposing to this disease is unknown and therefore needs to be discovered. The aim of this study was to identify novel breast cancer susceptibility genes from the interweaving BRCA/Fanconi anemia (FA) pathway. Five candidate genes — MERIT40, ABRAXAS, BRIP1, CHK1, and FANCA — were screened for mutations by utilizing conformation-sensitive gel electrophoresis and sequencing, or with multiplex ligation-dependent probe amplification in blood DNA samples of Finnish familial breast cancer patients. Investigation of the MERIT40 gene revealed novel nucleotide changes, being the first report on mutation screening of this gene. None of the observed alterations, however, appeared to be disease related, suggesting that germline mutations in MERIT40 are rare or absent in breast cancer patients. A missense alteration (c.1082G>A, leading to Arg361Gln) was identified in ABRAXAS in 3 out of 125 Northern Finnish breast cancer families (2.4%), but not in any of the 867 healthy controls. The prevalence of the mutation between familial and control cases was statistically significantly different (p=0.002). ABRAXAS c.1082G>A appears to have pathological significance based on its exclusive occurrence in cancer cases, evolutionary conservation, disruption of a putative nuclear localization signal, reduced nuclear localization of the protein, and defective accumulation at DNA damage sites. The BRIP1 (FANCJ) and CHK1 genes were screened for large genomic rearrangements, but no abnormalities were detected, ruling out a significant contribution to breast cancer susceptibility in the Northern Finnish population. A novel large heterozygous deletion was identified in the FANCA gene in one out of 100 breast cancer families, removing, Tiivistelmä BRCA1 ja BRCA2 ovat kaksi tärkeintä perinnöllisen rinta- ja munasarjasyövän alttiusgeeniä.

34. ATM, ATR and Mre11 complex genes in hereditary susceptibility to breast cancer

Author: Pylkäs, K. (Katri) and Pylkäs, K. (Katri)
Abstract: Mutations in BRCA1 and BRCA2 explain only about 20% of familial aggregation of breast cancer, suggesting involvement of additional susceptibility genes. In this study five DNA damage response genes, ATM, ATR, MRE11, NBS1 and RAD50, were considered as putative candidates to explain some of the remaining familial breast cancer risk, and were screened for germline mutations in families displaying genetic predisposition. Analysis of ATM indicated that clearly pathogenic mutations seem to be restricted to those reported in ataxia-telangiectasia (A-T). However, a cancer risk modifying effect was suggested for a combination of two ATM polymorphisms, 5557G>A and IVS38-8T>C, as this allele seemed to associate with bilateral breast cancer (OR 10.2, 95% CI 3.1–33.8, p = 0.001). The relevance of ATM mutations, originally identified in Finnish A-T patients, in breast cancer susceptibility was evaluated by a large case-control study. Two such alleles, 6903insA and 7570G>C, in addition to 8734A>G previously associated with breast cancer susceptibility, were observed. The overall mutation frequency in unselected cases (7/1124) was higher than in controls (1/1107), but a significantly elevated frequency was observed only in familial cases (6/541, p = 0.006, OR 12.4, 95% CI 1.5–103.3). These three mutations showed founder effects in their geographical occurrence, and had different functional consequences at protein level. In ATR no disease-related mutations were observed, suggesting that it is not a breast cancer susceptibility gene. The mutation screening of the Mre11 complex genes, MRE11, NBS1 and RAD50, revealed two novel potentially breast cancer associated alleles: NBS1 Leu150Phe and RAD50 687delT were observed in 2.0% (3/151) of the studied families. The subsequent study of newly diagnosed, unselected breast cancer cases indicated that RAD50 687delT is a relatively common low-penetrance susceptibility allele in Northern Finland (cases 8/317 vs. controls 6/1000, OR 4.3
