Research Abstract

We demonstrated that mutations in SPTAN1 cause West syndrome with myelination delay and atrophy of brain thought identification of a de novo microdeletion in a patient. We also clarified breakpoints of two balanced translocations, demonstrating involvement of abnormalities of SRGAP2 and MEF2C in epileptic encephalopathy. In addition, by whole exome sequencing, we identified mutations in KCNQ2 and CASK in patients with Ohtahara syndrome.
