Cortical malformations characterized by white matter-lined cleft or cyst associated with ISCHEMIA and hemorrhagic insults. Symptoms include delayed growth and development, HYPOTONIA; SEIZURES; SPASTIC HEMIPLEGIA and MACROCEPHALY; MICROCEPHALY; or HYDROCEPHALUS. Mutations in the genes encoding COLLAGEN TYPE IV are associated with familial types.
