Abstract: BRCA1-associated breast and ovarian cancer risks can be modified by common genetic variants. To identify further cancer risk-modifying loci, we performed a multi-stage GWAS of 11,705 BRCA1 carriers (of whom 5,920 were diagnosed with breast and 1,839 were diagnosed with ovarian cancer), with a further replication in an additional sample of 2,646 BRCA1 carriers. We identified a novel breast cancer risk modifier locus at 1q32 for BRCA1 carriers (rs2290854, P = 2.7 × 10(-8), HR = 1.14, 95% CI: 1.09-1.20). In addition, we identified two novel ovarian cancer risk modifier loci: 17q21.31 (rs17631303, P = 1.4 × 10(-8), HR = 1.27, 95% CI: 1.17-1.38) and 4q32.3 (rs4691139, P = 3.4 × 10(-8), HR = 1.20, 95% CI: 1.17-1.38). The 4q32.3 locus was not associated with ovarian cancer risk in the general population or BRCA2 carriers, suggesting a BRCA1-specific association. The 17q21.31 locus was also associated with ovarian cancer risk in 8,211 BRCA2 carriers (P = 2×10(-4)). These loci may lead to an improved understanding of the etiology of breast and ovarian tumors in BRCA1 carriers. Based on the joint distribution of the known BRCA1 breast cancer risk-modifying loci, we estimated that the breast cancer lifetime risks for the 5% of BRCA1 carriers at lowest risk are 28%-50% compared to 81%-100% for the 5% at highest risk. Similarly, based on the known ovarian cancer risk-modifying loci, the 5% of BRCA1 carriers at lowest risk have an estimated lifetime risk of developing ovarian cancer of 28% or lower, whereas the 5% at highest risk will have a risk of 63% or higher. Such differences in risk may have important implications for risk prediction and clinical management for BRCA1 carriers.

Abstract: The considerable uncertainty regarding cancer risks associated with inherited mutations of BRCA2 is due to unknown factors. To investigate whether common genetic variants modify penetrance for BRCA2 mutation carriers, we undertook a two-staged genome-wide association study in BRCA2 mutation carriers. In stage 1 using the Affymetrix 6.0 platform, 592,163 filtered SNPs genotyped were available on 899 young (

Abstract: Background: Genome-wide association studies (GWAS) identified variants at 19p13.1 and ZNF365 (10q21.2) as risk factors for breast cancer among BRCA1 and BRCA2 mutation carriers, respectively. We explored associations with ovarian cancer and with breast cancer by tumor histopathology for these variants in mutation carriers from the Consortium of Investigators of Modifiers of BRCA1/2 (CIMBA).Methods: Genotyping data for 12,599 BRCA1 and 7,132 BRCA2 mutation carriers from 40 studies were combined.Results: We confirmed associations between rs8170 at 19p13.1 and breast cancer risk for BRCA1 mutation carriers [HR, 1.17; 95% confidence interval (CI), 1.07–1.27; P = 7.42 × 10−4] and between rs16917302 at ZNF365 (HR, 0.84; 95% CI, 0.73–0.97; P = 0.017) but not rs311499 at 20q13.3 (HR, 1.11; 95% CI, 0.94–1.31; P = 0.22) and breast cancer risk for BRCA2 mutation carriers. Analyses based on tumor histopathology showed that 19p13 variants were predominantly associated with estrogen receptor (ER)-negative breast cancer for both BRCA1 and BRCA2 mutation carriers, whereas rs16917302 at ZNF365 was mainly associated with ER-positive breast cancer for both BRCA1 and BRCA2 mutation carriers. We also found for the first time that rs67397200 at 19p13.1 was associated with an increased risk of ovarian cancer for BRCA1 (HR, 1.16; 95% CI, 1.05–1.29; P = 3.8 × 10−4) and BRCA2 mutation carriers (HR, 1.30; 95% CI, 1.10–1.52; P = 1.8 × 10−3).Conclusions: 19p13.1 and ZNF365 are susceptibility loci for ovarian cancer and ER subtypes of breast cancer among BRCA1 and BRCA2 mutation carriers.Impact: These findings can lead to an improved understanding of tumor development and may prove useful for breast and ovarian cancer risk prediction for BRCA1 and BRCA2 mutation carriers.

Abstract: We report on 19 individuals with a recurrent de novo c.607C>T mutation in PACS1. This specific mutation gives rise to a recognizable intellectual disability syndrome. There is a distinctive facial appearance (19/19), characterized by full and arched eyebrows, hypertelorism with downslanting palpebral fissures, long eye lashes, ptosis, low set and simple ears, bulbous nasal tip, wide mouth with downturned corners and a thin upper lip with an unusual "wavy" profile, flat philtrum, and diastema of the teeth. Intellectual disability, ranging from mild to moderate, was present in all. Hypotonia is common in infancy (8/19). Seizures are frequent (12/19) and respond well to anticonvulsive medication. Structural malformations are common, including heart (10/19), brain (12/16), eye (10/19), kidney (3/19), and cryptorchidism (6/12 males). Feeding dysfunction is presenting in infancy with failure to thrive (5/19), gastroesophageal reflux (6/19), and gastrostomy tube placement (4/19). There is persistence of oral motor dysfunction. We provide suggestions for clinical work-up and management and hope that the present study will facilitate clinical recognition of further cases.

Abstract: CIMBA Consortium et al., PMID: 25849179, [Importance]: Limited information about the relationship between specific mutations in BRCA1 or BRCA2 (BRCA1/2) and cancer risk exists. [Objective]: To identify mutation-specific cancer risks for carriers of BRCA1/2. [Design, Setting, and Participants]: Observational study ofwomen whowere ascertained between 1937 and 2011 (median, 1999) and found to carry disease-associated BRCA1 or BRCA2 mutations. The international sample comprised 19 581 carriers of BRCA1 mutations and 11 900 carriers of BRCA2 mutations from 55 centers in 33 countries on 6 continents.We estimated hazard ratios for breast and ovarian cancer based on mutation type, function, and nucleotide position.We also estimated RHR, the ratio of breast vs ovarian cancer hazard ratios. A value of RHR greater than 1 indicated elevated breast cancer risk; a value of RHR less than 1 indicated elevated ovarian cancer risk. [Exposures]: Mutations of BRCA1 or BRCA2. [Main Outcomes and Measures]: Breast and ovarian cancer risks. [Results]: Among BRCA1 mutation carriers, 9052 women (46%) were diagnosed with breast cancer, 2317 (12%) with ovarian cancer, 1041 (5%) with breast and ovarian cancer, and 7171 (37%) without cancer. Among BRCA2 mutation carriers, 6180 women (52%) were diagnosed with breast cancer, 682 (6%) with ovarian cancer, 272 (2%) with breast and ovarian cancer, and 4766 (40%) without cancer. In BRCA1, we identified 3 breast cancer cluster regions (BCCRs) located at c.179 to c.505 (BCCR1; RHR = 1.46; 95%CI, 1.22-1.74; P = 2 × 10-6), c.4328 to c.4945 (BCCR2; RHR = 1.34; 95%CI, 1.01-1.78; P = .04), and c. 5261 to c.5563 (BCCR2', RHR = 1.38; 95%CI, 1.22-1.55; P = 6 × 10-9).We also identified an ovarian cancer cluster region (OCCR) from c.1380 to c.4062 (approximately exon 11) with RHR = 0.62 (95%CI, 0.56-0.70; P = 9 × 10-17). In BRCA2, we observed multiple BCCRs spanning c.1 to c.596 (BCCR1; RHR = 1.71; 95%CI, 1.06-2.78; P = .03), c.772 to c.1806 (BCCR1'; RHR = 1.63; 95%CI, 1.10-2.40; P = .01), and c.7394 to c.8904 (BCCR2; RHR = 2.31; 95%CI, 1.69-3.16; P = .00002).We also identified 3 OCCRs: the first (OCCR1) spanned c.3249 to c.5681 that was adjacent to c.5946delT (6174delT; RHR = 0.51; 95%CI, 0.44-0.60; P = 6 × 10-17). The second OCCR spanned c.6645 to c.7471 (OCCR2; RHR = 0.57; 95%CI, 0.41-0.80; P = .001). Mutations conferring nonsense-mediated decay were associated with differential breast or ovarian cancer risks and an earlier age of breast cancer diagnosis for both BRCA1 and BRCA2 mutation carriers. [Conclusions and Relevance]: Breast and ovarian cancer risks varied by type and location of BRCA1/2 mutations. With appropriate validation, these data may have implications for risk assessment and cancer prevention decision making for carriers of BRCA1 and BRCA2 mutations., Dr Antoniou and the CIMBA data management are funded by Cancer Research UK.

Abstract: Background Risk prediction models are widely used in clinical genetic counselling. Despite their frequent use, the genetic risk models BOADICEA, BRCAPRO, IBIS and extended Claus model (eCLAUS), used to estimate BRCA1/2 mutation carrier probabilities, have never been comparatively evaluated in a large sample from central Europe. Additionally, a novel version of BOADICEA that incorporates tumour pathology information has not yet been validated. Patients and methods Using data from 7352 German families we estimated BRCA1/2 carrier probabilities under each model and compared their discrimination and calibration. The incremental value of using pathology information in BOADICEA was assessed in a subsample of 4928 pedigrees with available data on breast tumour molecular markers oestrogen receptor, progesterone receptor and human epidermal growth factor 2. Results BRCAPRO (area under receiver operating characteristic curve (AUC)=0.80 (95% CI 0.78 to 0.81)) and BOADICEA (AUC=0.79 (0.78–0.80)), had significantly higher diagnostic accuracy than IBIS and eCLAUS (p

Abstract: In families with clustering of breast and ovarian cancer, molecular testing of the major susceptibility genes BRCA1/2 helps to identify patients with disease mutations and healthy persons at high risk who can participate in targeted intervention programs. We investigated 5559 families from the German Consortium for Hereditary Breast and Ovarian Cancer included between 1997 and 2008 and treated under clinical routine conditions. In each family an index patient/person had been screened for deleterious mutations in BRCA1/2. Healthy relatives agreed to predictive testing in 888 of 1520 BRCA1/2 mutation-positive families (58%). Of 2646 eligible unaffected first-degree relatives 1143 decided to be tested (43%). In 325 families with BRCA1/2-positive index patients one related BC/OC patient was tested and 39 (12.0%; 95% confidence interval: 8.7-16.0%) discrepant cases found. A second related individual was screened in 163 of 3388 (4.9%) families with BRCA1/2-negative index patient and in eight families a BRCA1/2 mutation was found. In BRCA1/2 mutation-positive families, BC/OC patients lacking the familial mutation have to be expected at a rather high rate. In families with BRCA1/2-negative index patient we recommend a second screening if another patient with a high probability of carrying a BRCA1/2 mutation is available.

Abstract: In this review, the national guidelines and recommendations for genetic testing for familial/hereditary breast cancer from the UK, France, the Netherlands and Germany were evaluated as to the inclusion criteria for genetic testing. In all four countries, access to genetic testing relies basically on the family history of breast and ovarian cancer. Similarities are obvious for most selection criteria. All four guidelines recommend embedding genetic testing within a framework of genetic counselling, and all agree to perform genetic testing first in an affected person. However, there are differences regarding the thresholds based on certain familial constellations, detailed description of selection criteria, the degree of relatedness between affected individuals and the counsellee, the age of diagnosis, the individual history of early onset breast cancer, bilateral breast cancer, the tumour morphology or the access to intensified surveillance. These differences and open questions not covered by the guidelines, e.g. on how to deal with phenocopies, unclassified variants, genetic variants in newly identified breast cancer susceptibility genes or with family constellations not fitting the criteria, are discussed. New evidence is usually slowly integrated into the guidelines. An exchange process towards the harmonization of the guidelines will ensure high quality health care across Europe.

Abstract: BRCA1 is a major gatekeeper of genomic stability. Acting in multiple central processes like double-strand break repair, centrosome replication, and checkpoint control, BRCA1 participates in maintaining genomic integrity and protects the cell against genomic instability. Chromosomal instability (CIN) as part of genomic instability is an inherent characteristic of most solid tumors and is also involved in breast cancer development. In this study, we determined the extent of CIN in 32 breast cancer tumors of women with a BRCA1 germline mutation compared to 62 unselected breast cancers. We applied fluorescence in situ hybridization (FISH) with centromere-specific probes for the chromosomes 1, 7, 8, 10, 17, and X and locus-specific probes for 3q27 (BCL6), 5p15.2 (D5S23), 5q31 (EGR1), 10q23.3 (PTEN), and 14q32 (IGH@) on formalin-fixed paraffin-embedded tissue microarray sections. Our hypothesis of an increased level of CIN in BRCA1-associated breast cancer could not be confirmed by this approach. Surprisingly, we detected no significant difference in the extent of CIN in BRCA1-mutated versus sporadic tumors. The only exception was the CIN value for chromosome 1. Here, the extent of CIN was slightly higher in the group of sporadic tumors.

Abstract: Purpose To estimate the risk for contralateral breast cancer in members of BRCA1- and BRCA2-positive families and to determine predictive risk factors. Patients and Methods A retrospective, multicenter, cohort study was performed from 1996 until 2008 and comprised 2,020 women with unilateral breast cancer (index patients, n = 978; relatives, n = 1.42) from 978 families who had a BRCA1 or BRCA2 mutation. Cox regression analysis was applied to assess the association of age at first breast cancer with time from first to contralateral breast cancer, stratified by the affected BRCA gene. Results The cumulative risk for contralateral breast cancer 25 years after first breast cancer was 47.4% (95% CI, 38.8% to 56.0%) for patients from families with BRCA1 or BRCA2 mutations. Members of families with BRCA1 mutations had a 1.6-fold (95% CI, 1.2-fold to 2.3-fold) higher risk of contralateral breast cancer than members of families with BRCA2 mutations. Younger age at first breast cancer was associated with a significantly higher risk of contralateral breast cancer in patients with BRCA1 mutation, and a trend was observed in patients with BRCA2 mutation. After 25 years, 62.9% (95% CI, 50.4% to 75.4%) of patients with BRCA1 mutation who were younger than 40 years of age at first breast cancer developed contralateral breast cancer, compared with only 19.6% (95% CI, 5.3% to 33.9%) of those who were older than 50 years of age at first breast cancer. Conclusion Contralateral breast cancer risk depends on age at first breast cancer and on the affected BRCA gene, and this risk should be considered in treatment planning.

Abstract: Infiltrating lobular breast cancer (ILBC) is a clinically and biologically distinct tumour entity defined by a characteristic linear cord invasion pattern and inactivation of the CDH1 tumour suppressor gene encoding for E-cadherin. ILBCs also lack beta-catenin expression and show aberrant cytoplasmic localization of the E-cadherin binding protein p120-catenin. The lack of a well-characterized ILBC cell line has hampered the functional characterization of ILBC cells in vitro. We report the establishment of a permanent ILBC cell line, named IPH-926, which was derived from a patient with metastatic ILBC. The DNA fingerprint of IPH-926 verified genetic identity with the patient and had no match among the human cell line collections of several international biological resource banks. IPH-926 expressed various epithelial cell markers but lacked expression of E-cadherin due to a previously unreported, homozygous CDH1 241ins4 frameshift mutation. Detection of the same CDH1 241ins4 mutation in archival tumour tissue of the corresponding primary ILBC proved the clonal origin of IPH-926 from this particular tumour. IPH-926 also lacked beta-catenin expression and showed aberrant cytoplasmic localization of p120-catenin. Array-CGH analysis of IPH-926 revealed a profile of genomic imbalances that included many distinct alterations previously observed in primary ILBCs. Spectral karyotyping of IPH-926 showed a hyperdiploid chromosome complement and numerous clonal, structural aberrations. IPH-926 cells were anti-cancer drug-resistant, clonogenic in soft agar, and tumourigenic in SCID mice. In xenograft tumours, IPH-926 cells recapitulated the linear cord invasion pattern that defines ILBCs. In summary, IPH-926 significantly extends the biological spectrum of the established breast cancer cell lines and will facilitate functional analyses of genuine human ILBC cells in vitro and in vivo.

Abstract: To ensure targeted treatment, it would be useful to know at the time of diagnosis whether a BRCA mutation is causally related to an individual breast cancer. The aim of this study was to investigate in an unselected series of breast cancer patients the value of incorporating morphological and immunohistochemical features for the selection of patients who may benefit from BRCA1 genetic testing. In a retrospective approach, histopathological results of tumors from 897 women were reevaluated regarding age at diagnosis, subtype of cancer, tumor grade, and estrogen (ER), progesterone (PR), and Her2/neu receptor status, as well as p53 and Ki67 status. In all, 142 tumors fulfilled morphological criteria indicative of a BRCA1 mutation. Of the 59 women willing to participate, 26 women concomitantly showed a positive family history. Pathogenic BRCA1 germline mutations were detected in 7 of 18 women (39%) (95% confidence interval=0.17–0.64). All BRCA1 -associated tumors were of high grade, invasive-ductal subtype, and PR and Her2/neu negative, and 91% of the tumors were negative for ER; 60% of the tumors showed a high expression of p53 and 60% a high expression of Ki67. There was a significant difference with respect to grading ( P = 0.001 for G3), ER negativity ( P = 0.0075), Ki67 ≥ 65% ( P = 0.0039), and triple negativity (i.e., ER − , PR − , Her2/neu − ) ( P = 0.0019) between tumors of mutation carriers and noncarriers.

Abstract: The close functional relationship between p53 and the breast cancer susceptibility genes BRCA1 and BRCA2 has promoted the investigation of various polymorphisms in the p53 gene as possible risk modifiers in BRCA1/2 mutation carriers. Specifically, two polymorphisms in p53, c.97-147ins16bp and p.Arg72Pro have been analysed as putative breast cancer susceptibility variants, and it has been recently reported that a p53 haplotype combining the absence of the 16-bp insertion and the presence of proline at codon 72 (No Ins-72Pro) was associated with an earlier age at the onset of the first primary tumour in BRCA2 mutation carriers in the Spanish population. In this study, we have evaluated this association in a series of 2932 BRCA1/2 mutation carriers from the Consortium of Investigators of Modifiers of BRCA1 and BRCA2.

17. Erblicher Brust/Ovarialkrebs

Author: Dorothea Gadzicki and Mechthild Neises
Subjects: Psychiatry and Mental health
Abstract: Die Identifikation der Gene BRCA (breast cancer gene) 1 und 2 in den Jahren 1994 und 1995 war die Voraussetzung fur die Diagnostik genetischer Grundlagen des familiaren Mamma- und Ovarialkarzinoms. Eine Mutation in einem dieser Gene ist der wichtigste Risikofaktor fur die Entstehung eines solchen Karzinoms. Etwa 5 bis 10% aller Mamma- und Ovarialkarzinome sind durch genetische Veranlagung bedingt. Die Moglichkeiten der pradiktiven Medizin konnen sowohl Entlastung, aber auch psychische Belastungen der Ratsuchenden nach sich ziehen. Die Kenntnis der eigenen Prognose oder die anderer innerhalb der Familie kann die Kommunikation innerhalb der Familie und damit die Familienbeziehungen belasten. Die in der Regel noch gesunde Frau wird in der Beratung oft zum ersten Mal damit konfrontiert, dass die Erkrankung potentiell alle in der Familie und auch sie im Laufe ihres Lebens betreffen kann. Diese emotionale Belastung sollte in besonderer Weise berucksichtigt werden. Dabei ist innerhalb der Familie die Autonomie aller mit einem Recht auf Wissen, aber auch Nicht-Wissen sicherzustellen.

Abstract: In chronic myeloid leukemia (CML), imatinib may reverse bone marrow fibrosis (MF). Whether the unfavorable prognosis of MF is also reversed and whether imatinib guarantees against evolution of MF are unclear as yet. Fifty-nine patients with Ph+ CML treated with > or = 400 mg imatinib/day were examined for MF in 6- to 12-month intervals. Imatinib effectively reversed initial MF (P

Abstract: Germline mutations in the tumor suppressor gene APC are the underlying cause of familial adenomatous polyposis, an autosomal-dominant cancer predisposition syndrome of the colorectum. Here, we describe a complex pathogenic rearrangement in the APC gene that was detected during deletion screening and transmitted throughout at least three generations. The rearrangement consists of a deletion of 604 bp in intron 4 that impairs the binding site of the reverse primer for exon 4 and of an insertion of 119 bp in exon 4 that interferes with the binding site of the multiplex ligation-dependent probe amplification (MLPA) probes for exon 4. The insertion is composed of three duplicated sequences derived from exon 4, intron 3, and intron 4, all in inverse direction. By transcript analysis, we found that the mutation results in complete skipping of exon 4 and that it leads to a frameshift. The rearrangement would not have been identified had it occurred outside the MLPA hybridization site. Our findings demonstrate that part of the pathogenic mutations remain undetected by routine methods. Moreover, MLPA and RNA analysis alone would have led to an incorrect interpretation of a genomic deletion of exon 4.

Abstract: Here we report on a male infant presenting the typical pattern of Jacobsen syndrome including trigonocephaly, thrombocytopenia, congenital heart defect, urethral stenosis, and partial agenesis of the corpus callosum. Conventional karyotyping, FISH, SKY and CGH analyses showed that the region distal to the MLL locus on 11q23 was lost and replaced by the distal region of 11p, leading to a partial trisomy of 11p and a partial monosomy of 11q. According to ISCN (1995) the karyotype can be described as 46,XY,add(11)(q2?3). ish 11ptel(D11S2071x3),11qtel(VIJyRM2072x1). Array-CGH analysis allowed us to narrow down the breakpoints to 11p15.1 and 11q24.1. Methylation analyses of genes located on 11p showed an increased level of the non-methylated paternal allele of the KCNQ1OT1 gene, confirming the concomitant presence of Beckwith-Wiedemann syndrome (BWS). The phenotype resulting from the 11q deletion seems to dominate the phenotype due to the distal 11p trisomy. Investigation of the parents revealed that this chromosomal rearrangement was caused by a paternal pericentric inversion inv(11)(p15q24). Since chromosomal aberrations like the one described here can easily be overlooked during routine chromosome analysis, combined FISH analysis using subtelomeric and possibly additional probes should be applied if there is any doubt about the integrity of telomeric regions.

Abstract: In a large Saudi Arabian family with hereditary hemorrhagic telangiectasia (HHT), we identified ACVRL1 (ALK1) nonsense mutation Q490X in 40 HHT patients and three healthy children, but neither in 11 individuals with epistaxis, 41 other healthy family members, nor in 50 healthy unrelated Saudi Arabian controls. Sequence analysis of the entire coding region of the ACVRL1 and ENG genes in five of the 11 epistaxic individuals did not reveal any other disease-causing mutation. Epistaxis seems to be a relatively common phenocopy of HHT in the family under study. One couple, both affected by HHT and carriers of Q490X, had 12 pregnancies. Three of them ended in spontaneous abortion, four in early neonatal death, and only five yielded living offspring, all of which had HHT and were Q490X heterozygous. This observation corroborates previous claims that homozygosity for HHT-causing mutations is lethal.

Abstract: Objectives: Fluorescence in situ hybridization (FISH) has become a useful tool to identify chromosomal aberrations in non-dividing cells. Numerous studies have compared chromosomal banding analysis (CBA) and FISH on fixed cultured bone marrow cells. However, up to now, there has been no study comparing two main sources of diagnostic material, i.e. bone marrow aspirates and trephine biopsies. We therefore analyzed these materials by FISH in comparison with CBA. Methods: CBA revealed chromosomal aberrations in 18 patients suffering from myelodysplastic syndrome (n = 13), acute myeloid leukemia (n = 3), or chronic myeloproliferative syndrome (n = 2). FISH was performed on fixed cultured bone marrow cells, aspirates and trephine biopsies from each patient. Results: Percentages of aberrant cells in the different materials correlated highly with Pearson values of 0.909 for biopsy/fixed cultured cells (p < 0.001), 0.830 for biopsy/aspirate (p < 0.001) and 0.768 for aspirate/fixed cultured cells (p < 0.001). Moreover, in bone marrow biopsies peritrabecular and central intertrabecular areas yielded very similar FISH results with a high correlation (r = 0.968, p < 0.001). FISH revealed a lower proportion of aberrant cells than CBA in 90% of the specimens. Conclusions: In summary, the different materials available for the FISH examination are comparable in sensitivity and show similar quantitative results. Therefore, the use of biopsy sections for the routine FISH examination of chromosomal abnormalities is a valid method.

Abstract: Fluorescence in situ hybridisation (FISH) has gained major impact in the detection of chromosomal aberrations. The application of FISH, however, is hampered due to complicated protocols. We therefore designed a FISH protocol that allows the fast and reliable application on cytological and histological specimens. Cytological and histological specimens of bone marrow, lymph nodes, liver and breast were analysed with 14 sets of centromere or locus-specific probes. A pretreatment of enzymatic digestion and microwave heating with the same incubation times for all specimens and probes used was performed. Hybridisation efficiency was proved by calculating the thresholds for monosomy, trisomy and translocations. Values in cytological specimens reached 9.0, 3.9 and 4.6%, respectively. In histological sections, values of 6.4% were seen for aneusomy and 3.1% for translocations. However, values for monosomy reached 20.5% in bone marrow and 61.8% in liver tissues due to cutting artifacts. In bone marrow with acute myeloid leukaemias, lymph nodes with follicular and mantle cell lymphomas, breast carcinomas and liver cell carcinomas, FISH confirmed aberrations already found using conventional cytogenetics. The protocol shown here is easy to perform and can be used with cytological and histological specimens. Moreover, with "hands on" time of less than 2 h, FISH can also be used for daily routine purposes.

Abstract: Imatinib mesylate was designed as an inhibitor targeting the BCR-ABL tyrosine kinase, the molecular counterpart of the Philadelphia translocation t(9;22)(q34;q11). We report on a patient with chronic myeloid leukemia (CML) undergoing acceleration during imatinib treatment. Cytogenetic analysis revealed four different cell populations: 46,XX,t(9;22)(q34;q11),der(18)t(2;18)(p11;p11)[1]/47,idem,i(17)(q10),-der(18)t(2;18),+der(22)t(9;22)[1]/46,idem,-t(9;22),der(9)t(9;22),ider(22)t(9;22)[12]/ 47,idem,-t(9;22),der(9)t(9;22),+22,ider(22)t(9;22)x2[1]. FISH analysis confirmed the presence of these four clones. Moreover, 49% of the interphase nuclei contained either one or two clustered fusion signals, indicating a low-level amplification of the BCR-ABL fusion gene. With quantitative real-time RT-PCR, a BCR-ABL/G6PDH ratio of 0.8 was determined, which is comparable to that measured in the K562 cell line with a known BCR-ABL amplification and which is increased by more than about 60-fold compared to a CML at diagnosis with >80% Philadelphia-positive cells. We give further evidence that the genomic BCR-ABL amplification results in an increased level of BCR-ABL transcript linking two potent mechanisms of resistance against imatinib treatment.

Abstract: Combining fluorescence R-banding, fluorescence in situ hybridization and spectral karyotyping allowed us to precisely define chromosomal breakpoints, gains, losses and a newly detected amplification in the human mantle cell lymphoma (MCL) cell line GRANTA-519. GRANTA-519 is characterized by the t(11;14)(q13;q32) resulting in overexpression of cyclin D1, a key player in cell cycle control. Hitherto unresolved complex rearrangements involve 1p, 1q, 3cen, 9p, 11q, 12p, 12q, 16p, 17p, and 18cen. Moreover, a 4- to 6-fold gain of sequences on 18q leads to a low-level amplification of the BCL2 gene and to an overexpression of the BCL2 protein. These results provide the basis for the identification of not only candidate oncogenes responsible for MCL in gained regions, but also for the identification of putative tumor suppressor genes in commonly deleted regions like 1p22, which would eventually enable functional studies of these genes.

Abstract: Tourette syndrome (TS) is a complex inherited disorder of unknown aetiology, characterized by multiple motor and vocal tics. Involvement of the central cannabinoid (CB1) system is suggested because of therapeutic effects of marijuana (Cannabis sativa L.) consumption and Delta(9)-tetrahydrocannabinol (-THC) treatment in TS patients. The central cannabinoid receptor (CNR1) gene encoding the CNR1 was considered as a candidate gene for TS and systematically screened by single-strand conformation polymorphism (SSCP) analysis and sequencing. Compared with the published CNR1 sequence, three single base substitutions were identified: 1326T --> A, 1359G --> A, 1419 + 1G --> C. The change at position 1359 is a common polymorphism (1359 G/A) without allelic association with TS. 1326T --> A was present in only one TS patient and is a silent mutation which does not change codon 442 (valine). 1419 + 1G --> C affects the first nucleotide immediately following the coding sequence. It was first detected in three of 40 TS patients and none of 81 healthy controls. This statistically significant association with TS (P = 0.034) could not be confirmed in two subsequent cohorts of 56 TS patients (one heterozygous for 1419 + 1G --> C) and 55 controls and 64 patients and 66 controls (one heterozygous for 1419 + 1G --> C), respectively. Transcript analysis of lymphocyte RNA from 5 1419 + 1G --> C carriers revealed no systematic influence on the expression level of the mutated allele. In addition, segregation analysis of 1419 + 1G --> C in affected families gave evidence that 1419 + 1G --> C does not play a causal role in the aetiology of TS. We conclude that genetic variations of the CNR1 gene are not a plausible explanation for the clinically observed relation between the cannabinoid system and TS.

Abstract: BRCA1-associated breast and ovarian cancer risks can be modified by common genetic variants. To identify further cancer risk-modifying loci, we performed a multi-stage GWAS of 11,705 BRCA1 carriers (of whom 5,920 were diagnosed with breast and 1,839 were diagnosed with ovarian cancer), with a further replication in an additional sample of 2,646 BRCA1 carriers. We identified a novel breast cancer risk modifier locus at 1q32 for BRCA1 carriers (rs2290854, P = 2.7×10−8, HR = 1.14, 95% CI: 1.09–1.20). In addition, we identified two novel ovarian cancer risk modifier loci: 17q21.31 (rs17631303, P = 1.4×10−8, HR = 1.27, 95% CI: 1.17–1.38) and 4q32.3 (rs4691139, P = 3.4×10−8, HR = 1.20, 95% CI: 1.17–1.38). The 4q32.3 locus was not associated with ovarian cancer risk in the general population or BRCA2 carriers, suggesting a BRCA1-specific association. The 17q21.31 locus was also associated with ovarian cancer risk in 8,211 BRCA2 carriers (P = 2×10−4). These loci may lead to an improved understanding of the etiology of breast and ovarian tumors in BRCA1 carriers. Based on the joint distribution of the known BRCA1 breast cancer risk-modifying loci, we estimated that the breast cancer lifetime risks for the 5% of BRCA1 carriers at lowest risk are 28%–50% compared to 81%–100% for the 5% at highest risk. Similarly, based on the known ovarian cancer risk-modifying loci, the 5% of BRCA1 carriers at lowest risk have an estimated lifetime risk of developing ovarian cancer of 28% or lower, whereas the 5% at highest risk will have a risk of 63% or higher. Such differences in risk may have important implications for risk prediction and clinical management for BRCA1 carriers., Author Summary BRCA1 mutation carriers have increased and variable risks of breast and ovarian cancer. To identify modifiers of breast and ovarian cancer risk in this population, a multi-stage GWAS of 14,351 BRCA1 mutation carriers was performed. Loci 1q32 and TCF7L2 at 10q25.3 were associated with breast cancer risk, and two loci at 4q32.2 and 17q21.31 were associated with ovarian cancer risk. The 4q32.3 ovarian cancer locus was not associated with ovarian cancer risk in the general population or in BRCA2 carriers and is the first indication of a BRCA1-specific risk locus for either breast or ovarian cancer. Furthermore, modeling the influence of these modifiers on cumulative risk of breast and ovarian cancer in BRCA1 mutation carriers for the first time showed that a wide range of individual absolute risks of each cancer can be estimated. These differences suggest that genetic risk modifiers may be incorporated into the clinical management of BRCA1 mutation carriers.

Abstract: BRD7 (bromodomain 7), a subunit of poly-bromo-associated BRG1-associated factor (PBAF)-specific Swi/Snf chromatin remodeling complexes, has been proposed as a tumour suppressor protein following its identification as an important component of both functional p53 and BRCA1 (breast cancer 1, early onset) pathways. As low BRD7 expression levels have been linked to p53-wild-type breast tumour cells, we hypothesized an implication of BRD7 germline alterations in the pathogenesis of hereditary breast cancer similar to that of TP53 in Li-Fraumeni syndrome. We performed sequence analysis of the BRD7 gene on 61 high-risk individuals with hereditary or very-early-onset breast cancer and 100 healthy controls. Four potentially disease-causing single-nucleotide alterations were detected within the cohort of breast cancer patients (one listed as a rare single-nucleotide polymorphism (SNP) in the NCBI (National Center for Biotechnology Information) SNP database). Two of the detected variants were also each found once within the control collective. Segregation analysis on both families of those carrying the remaining two variants revealed segregation of these BRD7 alterations independent of breast cancer. In conclusion, it seems that the BRD7 variants we detected represent rare polymorphisms and mainly rule out BRD7 as a frequent high-penetrance breast cancer susceptibility gene. However, further analyses in larger cohorts of women with hereditary breast cancer should clarify the role of BRD7 in breast cancer predisposition.

Abstract: INTRODUCTION: Several common alleles have been shown to be associated with breast and/or ovarian cancer risk for BRCA1 and BRCA2 mutation carriers. Recent genome-wide association studies of breast cancer have identified eight additional breast cancer susceptibility loci: rs1011970 (9p21, CDKN2A/B), rs10995190 (ZNF365), rs704010 (ZMIZ1), rs2380205 (10p15), rs614367 (11q13), rs1292011 (12q24), rs10771399 (12p11 near PTHLH) and rs865686 (9q31.2). METHODS: To evaluate whether these single nucleotide polymorphisms (SNPs) are associated with breast cancer risk for BRCA1 and BRCA2 carriers, we genotyped these SNPs in 12,599 BRCA1 and 7,132 BRCA2 mutation carriers and analysed the associations with breast cancer risk within a retrospective likelihood framework. RESULTS: Only SNP rs10771399 near PTHLH was associated with breast cancer risk for BRCA1 mutation carriers (per-allele hazard ratio (HR) = 0.87, 95% CI: 0.81 to 0.94, P-trend = 3 x 10-4). The association was restricted to mutations proven or predicted to lead to absence of protein expression (HR = 0.82, 95% CI: 0.74 to 0.90, P-trend = 3.1 x 10-5, P-difference = 0.03). Four SNPs were associated with the risk of breast cancer for BRCA2 mutation carriers: rs10995190, P-trend = 0.015; rs1011970, P-trend = 0.048; rs865686, 2df-P = 0.007; rs1292011 2df-P = 0.03. rs10771399 (PTHLH) was predominantly associated with estrogen receptor (ER)-negative breast cancer for BRCA1 mutation carriers (HR = 0.81, 95% CI: 0.74 to 0.90, P-trend = 4 x 10-5) and there was marginal evidence of association with ER-negative breast cancer for BRCA2 mutation carriers (HR = 0.78, 95% CI: 0.62 to 1.00, P-trend = 0.049). CONCLUSIONS: The present findings, in combination with previously identified modifiers of risk, will ultimately lead to more accurate risk prediction and an improved understanding of the disease etiology in BRCA1 and BRCA2 mutation carriers., published_or_final_version

Abstract: In 2004 the NICE guidelines on familial breast cancer advised Health Care Professionals that they should not actively seek to identify women with a family history of breast cancer. We have carried out a review of the evidence base and a large scale questionnaire survey of health professionals in four European countries. There is overwhelming support amongst GPs and surgeons against the premise that that health care professionals should not be proactive in identifying patients at risk of familial breast cancer. This that suggest the time is right to overturn the NICE decision.

Abstract: [Background]: Germline mutations in the BRCA1 and BRCA2 genes are associated with increased risks of breast and ovarian cancers. Although several common variants have been associated with breast cancer susceptibility in mutation carriers, none have been associated with ovarian cancer susceptibility. A genome-wide association study recently identified an association between the rare allele of the single-nucleotide polymorphism (SNP) rs3814113 (ie, the C allele) at 9p22.2 and decreased risk of ovarian cancer for women in the general population. We evaluated the association of this SNP with ovarian cancer risk among BRCA1 or BRCA2 mutation carriers by use of data from the Consortium of Investigators of Modifiers of BRCA1/2. [Methods]: We genotyped rs3814113 in 10 029 BRCA1 mutation carriers and 5837 BRCA2 mutation carriers. Associations with ovarian and breast cancer were assessed with a retrospective likelihood approach. All statistical tests were two-sided. [Results]: The minor allele of rs3814113 was associated with a reduced risk of ovarian cancer among BRCA1 mutation carriers (per-allele hazard ratio of ovarian cancer = 0.78, 95% confidence interval = 0.72 to 0.85; P = 4.8 × 10-9) and BRCA2 mutation carriers (hazard ratio of ovarian cancer = 0.78, 95% confidence interval = 0.67 to 0.90; P = 5.5 × 10-4). This SNP was not associated with breast cancer risk among either BRCA1 or BRCA2 mutation carriers. BRCA1 mutation carriers with the TT genotype at SNP rs3814113 were predicted to have an ovarian cancer risk to age 80 years of 48%, and those with the CC genotype were predicted to have a risk of 33%. [Conclusion]: Common genetic variation at the 9p22.2 locus was associated with decreased risk of ovarian cancer for carriers of a BRCA1 or BRCA2 mutation., Spanish National Cancer Center (CNIO) and the Spanish Consortium: Partially supported by Fundación Mutua Madrileña, Asociación Española Contra el Cáncer, and the Spanish Ministry of Science and Innovation (FIS PI08 1120).

Abstract: Dysregulation of apoptosis plays an important role in carcinogenesis. Therefore, apoptosis-associated genes like the death receptor 4 (DR4, TRAIL-R1) are interesting candidates for modifying the penetrance of breast and ovarian cancer in carriers of BRCA1 and BRCA2 mutations. The DR-4 haplotype 626C-683C [626C > G, Thr209Arg (rs4871857) and 683A > C, Glu228Ala (rs17088993)] has recently been linked to an increased risk of breast cancer. To evaluate whether DR4 626C > G or DR4 683A > C modifies the risk of breast or ovarian cancer in carriers of BRCA1 and BRCA2 mutations, we undertook a national multicenter study including data of 840 carriers of breast cancer gene (BRCA) mutations. DNA samples were collected from 12 German research centers between 1996 and 2005 and were genotyped by the Taqman allelic discrimination assay. The association between genotypes and incidence of breast or ovarian cancer data was evaluated using a Cox proportional hazards regression model. We found evidence for a significant association of DR4 683A > C with a higher risk for ovarian cancer in carriers of BRCA1 mutations [n = 557, hazard ratio 1.78 (1.24-2.55), p = 0.009]. Our results thus indicate that the DR4 683A > C variant modifies the risk of ovarian cancer in carriers of BRCA1 mutations.

Abstract: CHARGE syndrome is an autosomal dominant inherited multiple malformation disorder typically characterized by coloboma, choanal atresia, hypoplastic semicircular canal, cranial nerve defects, cardiovascular malformations and ear abnormalities. Mutations in the chromodomain helicase DNA-binding protein 7 (CHD7) gene are the major cause of CHARGE syndrome. Mutation analysis was performed in 18 patients with firm or tentative clinical diagnosis of CHARGE syndrome. In this study eight mutations distributed across the gene were found. Five novel mutations - one missense (c.2936Tandgt;C), one nonsense (c.8093Candgt;A) and three frameshift mutations (c.804_805insAT, c.1757_1770del14, c.1793delA) - were identified. As far as familial data were available these mutations were found to have arisen de novo. Comparison of the clinical features of patients with the same mutation demonstrates that expression of the phenotype is highly variable. The mutation detection rate in this study was 44.4% in patients with a clinically established or suspected diagnosis of CHARGE syndrome.

Abstract: To validate common low-risk variants predisposing for breast cancer (BC) in a large set of BRCA1/2 negative familial or genetically enriched cases from Germany, we genotyped 1,415 cases and 1,830 healthy women by MALDI-TOF in 105 candidate SNPs. Significantly higher ORs than previously reported for heterozygous unselected cases were found for the minor allele in FGFR2 (OR = 1.43, 95% CI 1.30-1.59, p-value = 1.24 x 10(-12)) and for TNRC9 (OR = 1.33, 95% CI 1.19-1.46, p-value = 1.54 x 10(-7)). Most intriguing, however, were the ORs for homozygous carriers from high-risk families for FGFR2 (OR = 2.05, 95% CI 1.68-2.51, LSP1 (OR = 0.49, 95% CI 0.28-0.86) and TNRC9 (OR = 1.62, 95% CI 1.27-2.07). Moreover, the additional validation of 99 CGEMS-SNPs identified putative novel susceptibility alleles within the LSP1 gene (OR = 0.73, 95% CI 0.61-0.87, p-value = 5.23 x 10(-4)). Finally, we provide evidence for the first time that a low-risk variant located at 6q22.33 (rs6569479) is associated with estrogen receptor negative BC in familial cases (OR = 1.33, 95% CI 1.06-1.66; p-value = 0.012). Our data confirm the impact of the previously identified susceptibility loci and provide preliminary evidence for novel susceptibility loci in familial BC cases and correlate them to specific histopathological subtypes defined by estrogen receptor status.

Abstract: Chromosome aberrations are important prognostic markers in multiple myeloma (MM), but their identification may be hampered by complexity of the karyotypes. Using multicolor fluorescence in situ hybridization (mFISH), we found cryptic aberrations in 7 of 10 patients with a complex karyotype. Moreover, in addition to typical aberrations involving 1q, 13q, 14q and 17p and structural aberrations in chromosomes 1, 6, 9 and 19, (iso)dicentric chromosomes and whole-arm translocations were detected. These chromosome aberrations were generated by breaks in heterochromatic regions indicating an increased breakage of these regions, which may predispose to the generation of chromosome aberrations in multiple myeloma.

Abstract: Breast cancer is the most common malignancy in women in the Western world. Except for the high breast cancer risk in BRCA1 and BRCA2 mutation carriers as well as the risk for breast cancer in certain rare syndromes caused by mutations in TP53, STK11, PTEN, CDH1, NF1 or NBN, familial clustering of breast cancer remains largely unexplained. Despite significant efforts, BRCA3 could not be identified, but several reports have recently been published on genes involved in DNA repair and single nucleotide polymorphisms (SNPs) associated with an increased breast cancer risk. Although candidate gene approaches demonstrated moderately increased breast cancer risks for rare mutations in genes involved in DNA repair (ATM, CHEK2, BRIP1, PALB2 and RAD50), genome-wide association studies identified several SNPs as low-penetrance breast cancer susceptibility polymorphisms within genes as well as in chromosomal loci with no known genes (FGFR2, TOX3, LSP1, MAP3K1, TGFB1, 2q35 and 8q). Some of these low-penetrance breast cancer susceptibility polymorphisms also act as modifier genes in BRCA1/BRCA2 mutation carriers. This review not only outlines the recent key developments and potential clinical benefit for preventive management and therapy but also discusses the current limitations of genetic testing of variants associated with intermediate and low breast cancer risk.

Abstract: As sequence analysis for BRCA1 and BRCA2 mutations is both time- and cost-intensive, current strategies often include scanning techniques to identify fragments containing genetic sequence alterations. However, a systematic assessment of the diagnostic accuracy has been lacking so far. Here, we report on a systematic review to assess the internal and external validity of current scanning techniques. Inclusion criteria were: controlled design, investigators blinded, and tests suitable as a scanning tool for the whole genes BRCA1 and BRCA2. Outcome parameters were sensitivity, specificity, and positive and negative predictive values compared to direct sequencing. Out of 3816 publications, 10 studies reporting on 12 methods met our inclusion criteria. The internal and external validity of most of these studies was limited. Sensitivities were reported to be 100% for enzymatic mutation detection (EMD), multiple-dye cleavase fragment length polymorphism (MD-CFLP), fluorescence-based conformation-sensitive gel electrophoresis (F-CSGE), RNA-based sequencing, restriction endonuclease fingerprinting-single strand conformation polymorphism (REF-SSCP), stop codon (SC) assay, and denaturing high-performance liquid chromatography (DHPLC). Sensitivity was 50-96% for SSCP, 88-91% for two-dimensional gene scanning (TDGS), 76% for conformation-sensitive gel electrophoresis (CSGE), 75% for protein truncation test (PTT), and 58% for micronucleus test (MNT). Specificities close to 100% were reported, except for MNT. PTT and SC assay are only able to detect truncating mutations. Most studies were designed to introduce new experimental approaches or modifications of established methods and require further evaluation. F-CSGE, REF-SSCP, RNA-based sequencing, EMD, and MD-CFLP will need further evaluation before their use in a routine setting can be considered. SSCP, MNT, PTT, CSGE, and TDGS cannot be recommended because of their low sensitivity. DHPLC outperforms all other methods studied. However, none of the four studies evaluating DHPLC was performed on BRCA2.

Abstract: Tourette syndrome (TS) is a complex inherited disorder of unknown aetiology, characterized by multiple motor and vocal tics. Involvement of the central cannabinoid (CB1) system is suggested because of therapeutic effects of marijuana (Cannabis sativa L.) consumption and Delta(9)-tetrahydrocannabinol (-THC) treatment in TS patients. The central cannabinoid receptor (CNR1) gene encoding the CNR1 was considered as a candidate gene for TS and systematically screened by single-strand conformation polymorphism (SSCP) analysis and sequencing. Compared with the published CNR1 sequence, three single base substitutions were identified: 1326T --A, 1359G --A, 1419 + 1G --C. The change at position 1359 is a common polymorphism (1359 G/A) without allelic association with TS. 1326T --A was present in only one TS patient and is a silent mutation which does not change codon 442 (valine). 1419 + 1G --C affects the first nucleotide immediately following the coding sequence. It was first detected in three of 40 TS patients and none of 81 healthy controls. This statistically significant association with TS (P = 0.034) could not be confirmed in two subsequent cohorts of 56 TS patients (one heterozygous for 1419 + 1G --C) and 55 controls and 64 patients and 66 controls (one heterozygous for 1419 + 1G --C), respectively. Transcript analysis of lymphocyte RNA from 5 1419 + 1G --C carriers revealed no systematic influence on the expression level of the mutated allele. In addition, segregation analysis of 1419 + 1G --C in affected families gave evidence that 1419 + 1G --C does not play a causal role in the aetiology of TS. We conclude that genetic variations of the CNR1 gene are not a plausible explanation for the clinically observed relation between the cannabinoid system and TS.

Abstract: 1013 Background: A high incidence of contralateral breast cancer has been reported in patients with BRCA1or BRCA2 mutations while the risk in patients with familial non-BRCA-associated breast cancer remains unclear. This study was undertaken to estimate the risk for contralateral breast cancer in patients of BRCA1- and BRCA2-negative high risk families and to determine predictive risk factors. Methods: A retrospective, multicenter, cohort study was performed from 1996 until 2010 and comprised 3,580 women with unilateral breast cancer from 2,793 high-risk families who were tested negative for BRCA1 or BRCA2 mutations. Kaplan-Meier analysis was used to estimate age-dependent contralateral breast cancer risks. Cox regression analysis was applied to assess the impact of age at first breast cancer on contralateral breast cancer risk. Results: The cumulative risk for contralateral breast cancer 25 years after first breast cancer was 19% (95%CI 16% to 22%) for patients from families with non-BRCA-associated brea...

Abstract: Abstract #3091 Background : In a multidisciplinary program supported by the German Cancer Aid in 1996-2006 a total of 3.408 women with a family history for breast and/or ovarian cancer were genetically counselled and tested for BRCA-1 and BRCA-2 mutations. Methods: The mutations were detected using DHPLC and direct sequencing. The family history of breast and/or ovarian cancer was proven by collecting medical reports of family members. The statistical analysis was done using standard procedures (Kaplan-Meier-analysis, t-test, chi-square-test). Results: Among the women with breast cancer 566 showed a deleterious BRCA1 and 313 a BRCA2 mutation. Four women were found to have mutations in both genes and 2.525 were BRCA-1/2 negative. In accordance with the literature we found the phenotype “hormone receptor negative and grade 3” as well as the medullary subtype significantly more often in BRCA1 associated breast cancers (74% vs. 24%, 63% vs. 42% and 10% vs. 5%). The median age of onset was significantly lower in BRCA1 mutation carriers (38 yrs) compared to BRCA2 mutation carriers (45 yrs) and women tested negative for BRCA1 and BRCA2 mutations (46 yrs) as well as sporadic breast cancer cases within these families (52 yrs). The median age of the 4 women with mutations in both genes was even lower (median age 33.5 yrs).
