Two novel EIF2S3 mutations associated with syndromic intellectual disability with severe microcephaly, growth retardation, and epilepsy.

Abstract excerpt

X-chromosome exome sequencing was performed to identify the genetic cause of syndromic intellectual disability in two unrelated families with suspected X-linked inheritance. In both families, affected males presented with severe intellectual disability, microcephaly, growth retardation, and epilepsy. A missense mutation (c.777T>G p.(Ile259Met)) and a frameshift mutation (c.1394_1397del p.(Ile465Serfs*4)) were...
