Abstract

Trabajo presentado al 6th Congress of the European Academy of Neurology, celebrado de forma virtual del 23 al 26 de mayo de 2020., [Background and aims]: The disintegrin metalloproteinase 10 (ADAM 10) us the main α-secretase acting in the non-amyloidogenic processing of the amyloid precursor protein. Some ADAM10 gene variants have been associated with higher susceptibility to develop late-onset disease, though a clear clinical-genetic correlate has not been reported yet. We present a family in whom development of AD was associated with a nonsense ADAM10 prodomain mutation (p.Tyr167*) causing haploinsufficiency, [Methods]: Clinical-genetic and CSF biomarker study of a family with AD., [Results]: The p.Tyr167* mutation was absent from public databases and segregated with the disease. Age at onset for 3 affected siblings ranged from 58 to 68 years, and their clinical phenotypes have been noteworthy for the slow disease evolution. CSF Ab42, total tau, and phosphorylated tau biomarkers were consistent with AD. Haploinsufficiency was demonstrated by: a) ADAM10 isoforms in CSF decreased around 50%, and b) 70% reduction of CSF sAPPα peptide, both compared to controls. Sporadic AD cases had a similar decrease in CSF ADAM10 levels to that of mutants, though their sAPPα levels resembled those of controls., [Conclusion]: This family provides the first example of a deleterious coding variant in ADAM10 associated with familial AD, and further implicates the amyloidogenic process in the development of the disease. Similarities between clinical and biomarker findings suggest that this family could represent a genetic model of sporadic late-onset AD due to an age-related down-regulation of α-secretase.

Abstract

BACKGROUND: Sanger sequencing, still the standard technique for genetic testing in most diagnostic laboratories and until recently widely used in research, is gradually being complemented by next-generation sequencing (NGS). No single mutation detection technique is however perfect in identifying all mutations. Therefore, we wondered to what extent inconsistencies between Sanger sequencing and NGS affect the molecular diagnosis of patients. Since mutations in SCN1A, the major gene implicated in epilepsy, are found in the majority of Dravet syndrome (DS) patients, we focused on missed SCN1A mutations. METHODS: We sent out a survey to 16 genetic centers performing SCN1A testing. RESULTS: We collected data on 28 mutations initially missed using Sanger sequencing. All patients were falsely reported as SCN1A mutation-negative, both due to technical limitations and human errors. CONCLUSION: We illustrate the pitfalls of Sanger sequencing and most importantly provide evidence that SCN1A mutations are an even more frequent cause of DS than already anticipated.

19. De novotruncating mutation in SCN1Aas a cause of febrile seizures plus(FS+)

Author

Jaimes, Alex, Guerrero‐López, Rosa, González‐Giráldez, Beatriz, and Serratosa, Jose M.

Abstract

SCN1Ais one of the most relevant epilepsy genes. In general, de novosevere mutations, such as truncating mutations, lead to a classic form of Dravet syndrome (DS), while missense mutations are associated with both DS and milder phenotypes within the GEFS+ spectrum, however, these phenotype‐genotype correlations are not entirely consistent. Case report. We report an 18‐year‐old woman with a history of recurrent febrile generalized tonic‐clonic seizures (GTCS) starting at age four months and afebrile asymmetric GTCS and episodes of arrest, suggestive of focal impaired awareness seizures, starting at nine months. Her psychomotor development was normal. Sequencing of SCN1Arevealed a heterozygous de novotruncating mutation (c.5734C>T, p.Arg1912X) in exon 26. Conclusion. Truncating mutations in SCN1Amay be associated with milder phenotypes within the GEFS+ spectrum. Accordingly, SCN1Agene testing should be performed as part of the assessment for sporadic patients with mild phenotypes that fit within the GEFS+ spectrum, since the finding of a mutation has diagnostic, therapeutic and genetic counselling implications.

Abstract

OBJECTIVE: To identify the genetic cause of autosomal dominant Familial Focal Epilepsy with Variable Foci (FFEVF), to investigate the prevalence of mutations in the FFEVF causative gene in familial cases of non-lesional focal epilepsy, to study the expression in the brain and the subcellular localization of the encoded protein. BACKGROUND: FFEVF is characterized by seizures arising from different cortical regions in different affected family members. Brain imaging is normal. Seizure onset varies from infancy to adult life. Affected individuals occasionally have neuropsychiatric co-morbidities. Linkage studies mapped FFEVF to chromosome 22q12, but the causative gene had so far eluded identification. DESIGN/METHODS: We applied exome sequencing to two FFEVF families previously linked to chromosome 22q12, identifying DEPDC5 as the most likely candidate gene. We sequenced DEPDC5 in six additional 22q12-linked families and scanned DEPDC5 for sequence variation in 82 unrelated probands from families with at least two individuals with non-lesional focal epilepsy. We used qRT-PCR, immunofluorescence and western blot analysis to study DEPDC5 expression and subcellular localization. RESULTS: Heterozygous mutations in DEPDC5 were identified in 7/8 FFEVF families linked to chromosome 22q12 and in 10/82 (12.2%) probands from the small families with focal epilepsy. Each DEPDC5 mutation segregated with the FFEVF phenotype in the respective family and was absent in both dbSNP135 and an in-house exome sequencing database of 710 chromosomes. Most mutations caused premature termination codons suggesting haploinsufficiency as pathogenic mechanism. DEPDC5 encodes a1604 amino acid protein of unknown function, probably implicated in modulation of intracellular signaling.Mouse Depdc5 transcripts were detected at low levels in all brain regions and throughout brain development. Immunofluorescence analyses in mouse and human brain showed specific expression in neurons and perinuclear localization. CONCLUSIONS: Our findings establish DEPDC5 mutations as the most common known cause of familial focal epilepsy and identify a novel pathogenic pathway for epilepsy.

Abstract

Pediatric epilepsies are a group of disorders with a broad phenotypic spectrum that are associated with great genetic heterogeneity, thus making sequential single-gene testing an impractical basis for diagnostic strategy. The advent of next-generation sequencing has increased the success rate of epilepsy diagnosis, and targeted resequencing using genetic panels is the a most cost-effective choice. We report the results found in a group of 87 patients with epilepsy and developmental delay using targeted next generation sequencing (custom-designed Haloplex panel). Using this gene panel, we were able to identify disease-causing variants in 17 out of 87 (19.5%) analyzed patients, all found in known epilepsy-associated genes (KCNQ2, CDKL5, STXBP1, SCN1A, PCDH19, POLG, SLC2A1, ARX, ALG13, CHD2, SYNGAP1, and GRIN1). Twelve of 18 variants arose de novo and 6 were novel. The highest yield was found in patients with onset in the first years of life, especially in patients classified as having early-onset epileptic encephalopathy. Knowledge of the underlying genetic cause provides essential information on prognosis and could be used to avoid unnecessary studies, which may result in a greater diagnostic cost-effectiveness.

Abstract

Background: Patients with primary progressive aphasia (PPA) usually develop significant behavioral disturbances with progression of the disease. We tested our clinical observation that development of disruptive agitation is more likely in semantic than in nonfluent PPA and examined which clinical variables could be associated with this behavior. Methods: We retrospectively analyzed neuropsychiatric scores and the need for behavioral treatments in semantic PPA (n = 41) and nonfluent PPA (n = 39) cases and compared first (1-3 years since the onset of symptoms) and last (5-13 years since the onset) evaluations. Clinical variables and laterality of temporal atrophy were associated with symptoms in semantic PPA cases. Results: The semantic PPA group developed more frequent (p = 0.03) and intense agitation (p = 0.0008) and had a greater need for antipsychotic drugs (p = 0.001) than the nonfluent PPA group. Presence of agitation was clearly associated with psychotic symptoms (delusions/hallucinations) but was not associated with gender, age at onset, duration of the disease, or laterality of temporal atrophy. In contrast, nonfluent PPA cases were more frequently depressed and treated with antidepressants (p = 0.0007). There were no differences in anxiety, irritability, apathy, perseverations, hyperorality, or abnormal motor behavior. Conclusions: Semantic PPA in advanced disease is frequently associated with agitation and psychotic symptoms with fewer mood symptoms, while nonfluent PPA maintains a high prevalence of depression. This implies different treatment and care and support needs for each group. [ABSTRACT FROM AUTHOR]

29. C9ORF72hexanucleotide expansions of 20–22 repeats are associated with frontotemporal deterioration

Author

Abstract

Expansions of more than 30 hexanucleotide repetitions in the C9ORF72gene are a common cause of frontotemporal dementia (FTD) or amyotrophic lateral sclerosis (ALS). However, the range of 20–30 repetitions is rarely found and still has unclear significance. A screening of our cohort of cases with FTD (n = 109) revealed 4 mutation carriers (>30 repetitions) but also 5 probands with 20–22 confirmed repetitions. This study explored the possible pathogenic correlation of the 20–22 repeats expansion (short expansion).

Abstract

BACKGROUND: Genetic generalised epilepsy is the most common type of inherited epilepsy. Despite a high concordance rate of 80% in monozygotic twins, the genetic background is still poorly understood. We aimed to investigate the burden of rare genetic variants in genetic generalised epilepsy.METHODS: For this exome-based case-control study, we used three different genetic generalised epilepsy case cohorts and three independent control cohorts, all of European descent. Cases included in the study were clinically evaluated for genetic generalised epilepsy. Whole-exome sequencing was done for the discovery case cohort, a validation case cohort, and two independent control cohorts. The replication case cohort underwent targeted next-generation sequencing of the 19 known genes encoding subunits of GABAA receptors and was compared to the respective GABAA receptor variants of a third independent control cohort. Functional investigations were done with automated two-microelectrode voltage clamping in Xenopus laevis oocytes.FINDINGS: Statistical comparison of 152 familial index cases with genetic generalised epilepsy in the discovery cohort to 549 ethnically matched controls suggested an enrichment of rare missense (Nonsyn) variants in the ensemble of 19 genes encoding GABAA receptors in cases (odds ratio [OR] 2·40 [95% CI 1·41-4·10]; pNonsyn=0·0014, adjusted pNonsyn=0·019). Enrichment for these genes was validated in a whole-exome sequencing cohort of 357 sporadic and familial genetic generalised epilepsy cases and 1485 independent controls (OR 1·46 [95% CI 1·05-2·03]; pNonsyn=0·0081, adjusted pNonsyn=0·016). Comparison of genes encoding GABAA receptors in the independent replication cohort of 583 familial and sporadic genetic generalised epilepsy index cases, based on candidate-gene panel sequencing, with a third independent control cohort of 635 controls confirmed the overall enrichment of rare missense variants for 15 GABAA receptor genes in cases compared with controls (OR 1·46 [95% CI 1·02-2·08]; pNonsyn=0·013, adjusted pNonsyn=0·027). Functional studies for two selected genes (GABRB2 and GABRA5) showed significant loss-of-function effects with reduced current amplitudes in four of seven tested variants compared with wild-type receptors.INTERPRETATION: Functionally relevant variants in genes encoding GABAA receptor subunits constitute a significant risk factor for genetic generalised epilepsy. Examination of the role of specific gene groups and pathways can disentangle the complex genetic architecture of genetic generalised epilepsy.FUNDING: EuroEPINOMICS (European Science Foundation through national funding organisations), Epicure and EpiPGX (Sixth Framework Programme and Seventh Framework Programme of the European Commission), Research Unit FOR2715 (German Research Foundation and Luxembourg National Research Fund).

Abstract

International audience; OBJECTIVE: There is controversy about the clinical consequences of intermediate alleles (IAs) in Huntington disease (HD). The main objective of this study was to establish the clinical manifestations of IA carriers for a prospective, international, European HD registry.METHODS: We assessed a cohort of participants at risk with RESULTS: Of 12,190 participants, 657 (5.38%) with CONCLUSIONS: Although aging worsened the UHDRS scores independently of the genetic status, IAs might confer a late-onset abnormal motor and cognitive phenotype. These results might have important implications for genetic counseling.CLINICALTRIALSGOV IDENTIFIER: NCT01590589.

Abstract

De novo GRIN variants, encoding for the ionotropic glutamate NMDA receptor subunits, have been recently associated with GRIN-related disorders, a group of rare paediatric encephalopathies. Current investigational and clinical efforts are focused to functionally stratify GRIN variants, towards precision therapies of this primary disturbance of glutamatergic transmission that affects neuronal function and brain. In the present study, we aimed to comprehensively delineate the functional outcomes and clinical phenotypes of GRIN protein truncating variants (PTVs)-accounting for ~20% of disease-associated GRIN variants-hypothetically provoking NMDAR hypofunctionality. To tackle this question, we created a comprehensive GRIN PTVs variants database compiling a cohort of nine individuals harbouring GRIN PTVs, together with previously identified variants, to build-up an extensive GRIN PTVs repertoire composed of 293 unique variants. Genotype-phenotype correlation studies were conducted, followed by cell-based assays of selected paradigmatic GRIN PTVs and their functional annotation. Genetic and clinical phenotypes meta-analysis revealed that heterozygous GRIN1, GRIN2C, GRIN2D, GRIN3A and GRIN3B PTVs are non-pathogenic. In contrast, heterozygous GRIN2A and GRIN2B PTVs are associated with specific neurological clinical phenotypes in a subunit- and domain-dependent manner. Mechanistically, cell-based assays showed that paradigmatic pathogenic GRIN2A and GRIN2B PTVs result on a decrease of NMDAR surface expression and NMDAR-mediated currents, ultimately leading to NMDAR functional haploinsufficiency. Overall, these findings contribute to delineate GRIN PTVs genotype-phenotype association and GRIN variants stratification. Functional studies showed that GRIN2A and GRIN2B pathogenic PTVs trigger NMDAR hypofunctionality, and thus accelerate therapeutic decisions for this neurodevelopmental condition., (© The Author(s) 2020.

Abstract

Background: Sanger sequencing, still the standard technique for genetic testing in most diagnostic laboratories and until recently widely used in research, is gradually being complemented by next-generation sequencing (NGS). No single mutation detection technique is however perfect in identifying all mutations. Therefore, we wondered to what extent inconsistencies between Sanger sequencing and NGS affect the molecular diagnosis of patients. Since mutations in SCN1A, the major gene implicated in epilepsy, are found in the majority of Dravet syndrome (DS) patients, we focused on missed SCN1A mutations., Methods: We sent out a survey to 16 genetic centers performing SCN1A testing., Results: We collected data on 28 mutations initially missed using Sanger sequencing. All patients were falsely reported as SCN1A mutation-negative, both due to technical limitations and human errors., Conclusion: We illustrate the pitfalls of Sanger sequencing and most importantly provide evidence that SCN1A mutations are an even more frequent cause of DS than already anticipated.
