Abstract

Both mild and severe epilepsies are influenced by variants in the same genes, yet an explanation for the resulting phenotypic variation is unknown. As part of the ongoing Epi25 Collaboration, we performed a whole-exome sequencing analysis of 13,487 epilepsy-affected individuals and 15,678 control individuals. While prior Epi25 studies focused on gene-based collapsing analyses, we asked how the pattern of variation within genes differs by epilepsy type. Specifically, we compared the genetic architectures of severe developmental and epileptic encephalopathies (DEEs) and two generally less severe epilepsies, genetic generalized epilepsy and non-acquired focal epilepsy (NAFE). Our gene-based rare variant collapsing analysis used geographic ancestry-based clustering that included broader ancestries than previously possible and revealed novel associations. Using the missense intolerance ratio (MTR), we found that variants in DEE-affected individuals are in significantly more intolerant genic sub-regions than those in NAFE-affected individuals. Only previously reported pathogenic variants absent in available genomic datasets showed a significant burden in epilepsy-affected individuals compared with control individuals, and the ultra-rare pathogenic variants associated with DEE were located in more intolerant genic sub-regions than variants associated with non-DEE epilepsies. MTR filtering improved the yield of ultra-rare pathogenic variants in affected individuals compared with control individuals. Finally, analysis of variants in genes without a disease association revealed a significant burden of loss-of-function variants in the genes most intolerant to such variation, indicating additional epilepsy-risk genes yet to be discovered. Taken together, our study suggests that genic and sub-genic intolerance are critical characteristics for interpreting the effects of variation in genes that influence epilepsy.

Abstract

See Hansen and Møller (doi:10.1093/brain/awz318) for a scientific commentary on this article. Using polygenic risk scores from a genome-wide association study in generalized and focal epilepsy, Leu et al. reveal a significantly higher genetic burden for epilepsy in multiple cohorts of people with epilepsy compared to population controls. Quantification of common variant burden may be valuable for epilepsy prognosis and treatment., Rare genetic variants can cause epilepsy, and genetic testing has been widely adopted for severe, paediatric-onset epilepsies. The phenotypic consequences of common genetic risk burden for epilepsies and their potential future clinical applications have not yet been determined. Using polygenic risk scores (PRS) from a European-ancestry genome-wide association study in generalized and focal epilepsy, we quantified common genetic burden in patients with generalized epilepsy (GE-PRS) or focal epilepsy (FE-PRS) from two independent non-Finnish European cohorts (Epi25 Consortium, n = 5705; Cleveland Clinic Epilepsy Center, n = 620; both compared to 20 435 controls). One Finnish-ancestry population isolate (Finnish-ancestry Epi25, n = 449; compared to 1559 controls), two European-ancestry biobanks (UK Biobank, n = 383 656; Vanderbilt biorepository, n = 49 494), and one Japanese-ancestry biobank (BioBank Japan, n = 168 680) were used for additional replications. Across 8386 patients with epilepsy and 622 212 population controls, we found and replicated significantly higher GE-PRS in patients with generalized epilepsy of European-ancestry compared to patients with focal epilepsy (Epi25: P = 1.64×10−15; Cleveland: P = 2.85×10−4; Finnish-ancestry Epi25: P = 1.80×10−4) or population controls (Epi25: P = 2.35×10−70; Cleveland: P = 1.43×10−7; Finnish-ancestry Epi25: P = 3.11×10−4; UK Biobank and Vanderbilt biorepository meta-analysis: P = 7.99×10−4). FE-PRS were significantly higher in patients with focal epilepsy compared to controls in the non-Finnish, non-biobank cohorts (Epi25: P = 5.74×10−19; Cleveland: P = 1.69×10−6). European ancestry-derived PRS did not predict generalized epilepsy or focal epilepsy in Japanese-ancestry individuals. Finally, we observed a significant 4.6-fold and a 4.5-fold enrichment of patients with generalized epilepsy compared to controls in the top 0.5% highest GE-PRS of the two non-Finnish European cohorts (Epi25: P = 2.60×10−15; Cleveland: P = 1.39×10−2). We conclude that common variant risk associated with epilepsy is significantly enriched in multiple cohorts of patients with epilepsy compared to controls—in particular for generalized epilepsy. As sample sizes and PRS accuracy continue to increase with further common variant discovery, PRS could complement established clinical biomarkers and augment genetic testing for patient classification, comorbidity research, and potentially targeted treatment.

Abstract

Aim: We aimed to detect the utility of head up tilt test with video electroencephalography (EEG) in children with unexplained, recurrent loss of consciousness episodes. Method: Video EEG were recorded during the head up tilt test. The test was terminated if syncope or presyncope with 30% decrease in heart rate and/or systolic blood pressure occurred. Regarding encephalography, average amplitudes and frequencies at the baseline, tilt up position, presyncope, syncope and post-syncope period were evaluated from frontal, temporal and parieto-occipital areas. Results: There were 29 children (23 girl, 6 boy), with a mean age 13.83 +/- 3.3 years who had at least two syncopal attacks. Head up tilt test combined with video EEG was diagnostic in 12/29 patient (41.4%). 8/12 of the patients developed syncope attack and 4/12 of the patients developed presyncope attacks. Four (33.3%) of the patients with syncope attack had associated involuntary movements (3 vasodepressor, 1 mixed type). In the tilt positive group, there were significant differences in the amplitudes of frontal regions between the baseline and presyncope period (p=0.016 and 0.027, right and left hemispheres, respectively). There were also significant differences in the amplitudes of frontal and parieto-occipital regions and in the frequencies involving the bilateral parieto-occipital regions of the baseline and syncope period (p

Abstract

Yis U, Scheper GC, Uran N, Unalp A, Cakmakci H, Hiz-Kurul S, Dirik E, van der Knaap MS. Two cases with megalencephalic leukoencephalopathy with subcortical cysts and MLC1 mutations in the Turkish population. Turk J Pediatr 2010; 52: 179-183. Megalencephalic leukoencephalopathy with subcortical cysts is a rare leukodystrophy that is characterized by macrocephaly and a slowly progressive clinical course. It is one of the most commonly reported leukoencephalopathies in Turkey. Mutations in the MLC1 gene are the main cause of the disease. We report two patients with megalencephalic leukoencephalopathy with subcortical cysts with confirmed mutations in the MLC1 gene. The mutation in the second patient was novel. We also review identified mutations in the Turkish population

Abstract

Aim: The aim of this study is to evaluate clinical and radiological findings of cases with subacute sclerosing panencephalitis that are followed in Gaziantep Children's Hospital. Material and Method: Clinical onset findings, clinical progress and radiologic findings were evaluated. A total of 33 regularly followed cases were introduced to the study. Results: Mean age, disease onset age, age of measles infection and latent period were 10.53±2.37 years, 7.93±1.84 years, 13.06±8.85 months and 6.96±1.99 years, respectively. Seventy eight percent of the cases (n=26) were males and 22% of the cases were females. Fifty two percent of the cases (n=18) were in stage 3a. Ninety seven percent of the cases (n=32) had history of measles infection and 42% of the cases (n=14) were not vaccinated. The most presenting symptom was head drop and 60% of the cases (n=14) underwent brain magnetic resonance imaging. The most common radiologic abnormality was periventricular and subcortical white matter changes which were detected in T2 imaging series. Fifty two percent of the cases (n=17) had ongoing seizures and the most common seizure type was myoclonic seizures. Eighty eight percent of the cases (n=29) were not going to physical rehabilitation and 67% of the cases (n=22) had contractures. Conclusions: Subacute sclerosing panencephalitis is still an important health problem in developing countries. Families should be encouraged for physical rehabilitation programme to prevent contractures and improve quality of life. [ABSTRACT FROM AUTHOR]

Abstract

Aim: The aim of this study is to evaluate clinical and radiological features of our cases with congenital muscular dystrophy. Material and Method: The data of cases who were diagnosed with congenital muscular dystrophy in the Division of Pediatric Neurology of Dokuz Eylül University School of Medicine between July 2005 and July 2008 were analysed retrospectively. Results: A total of 13 cases were evaluated. Among the 13 cases, seven (53%) were boys and six (47%) were girls. Seven patients (53%) were in the alfa dystroglycanopathy group, five patients (38%) were in collagen VI related congenital muscular dystrophy group and one patient (9%) was in 'rigid spine' group. The mean age of cases with alfa dystroglycanopathy and collagen VI related congenital muscular dystrophy were 3.57±2.92 (0.5-7) and 10.83±5.67 (1-16) years, respectively. In alfa dystroglycanopathy group, five cases (71%) had eye involvement and six cases (85%) had developmental malformations of the central nervous system. All cases had brainstem hypoplasia and six cases (85%) had cerebellar cysts. In collagen VI related congenital muscular dystrophy group, the main complaints were retardation in motor mile stones, contractures in proximal joints and hyperlaxicity in distal joints. The most important clinical features in the case diagnosed with 'rigid spine' syndrome were severe scoliosis and muscle atrophy. Conclusions: The clinical features of congenital muscular dystrophies are heterogenous and increase in number of cases diagnosed as congenital muscular dystrophy should give an opportunity to determine the incidence of different types of congenital muscular dystrophies in our country.
