Polymicrogyria is a particular form of congenital brain malformation due to an excessive number of small and sometimes malformed gyri. In a recent publication in Neurology, mutations in FIG4 are described in a familial form of polymicrogyria. However, the FIG4 gene is no stranger in the field of neurogenetics. Continue reading
