Comprehensive EMX2 genotyping of a large schizencephaly case series

Schizencephaly is a brain malformation disorder characterized by one or more full-thickness Clefts through the cerebral cortex. While initial reports suggested that EMX2 imitations are a common cause of schizencephaly, more recent evidence suggests that EMX2 mutations are not a common cause Of this malformation. To determine the frequency of EMX2 mutations in patients with schizencephaly, we sequenced EMX2 in a cohort of 84 affected probands. Nopathologic mutations were identified in this cohort, suggesting that EMX2 mutations are an uncommon cause of schizencephaly. (c) 2007 Wiley-Liss, Inc.
