Cortical Malformations, Occipital; Occm

Description

Occipital cortical malformations (OCCM) is an autosomal recessive condition in which affected individuals develop seizures, sometimes associated with transient visual changes. Brain MRI shows both pachygyria and polymicrogyria restricted to the lateral occipital lobes (summary by Barak et al., 2011).
