Green List (high evidence)

Complex cortical dysplasia with other brain malformations (CDCBM) is a disorder of aberrant neuronal migration and disturbed axonal guidance. Affected individuals have mild to severe DD/ID, strabismus, axial hypotonia, and spasticity. Seizures reported in some.

Brain imaging shows variable malformations of cortical development, including polymicrogyria, gyral disorganization, and fusion of the basal ganglia, as well as thin corpus callosum, hypoplastic brainstem, and dysplastic cerebellar vermis. Extraocular muscles are not involved.

Multiple unrelated families reported. Note variants in this gene are also associated with CFEOM.
