Publications of the week – DOCK7, DEPDC5 and the yield of diagnostic gene panels

This week in epilepsy genetics. The following publications are a selection of what was published in the last week. These studies might be relevant for you because they both extend the phenotype of recent gene findings and describe novel genes that you should be aware of. Continue reading

A new spectrum unfolding – KCNT1 mutations in ADNFLE and MMPSI

A surprising finding. The genetic basis of many epileptic encephalopathies and familial epilepsies remains unknown. Novel sequencing technologies such as Next Generation Sequencing now offer the possibility to identify the genetic basis of these conditions. However, it is a rare event that a single gene is implicated in two completely different epilepsy subtypes. Such a finding has now been reported in Nature Genetics. The KCNT1 gene is found to be mutated in Malignant Migrating Partial Seizures of Infancy (MMPSI) and a severe form of Autosomal Dominant Nocturnal Frontal Lobe Epilepsy (ADNFLE). I doublechecked at least three times whether both papers actually talk about the same gene. Continue reading
