A pachygyria-polymicrogyria syndrome with many features overlapping those of Walker-Warburg and cerebro-oculo-muscular syndromes. The phenotype consists of congenital brain abnormalities, mainly type II or hydrocephalic lissencephaly (smoothness of the brain) and polymicrogyria (development of numerous small convolutions of the brain) in association with muscular dystrophy, ocular defects with visual failure, mental retardation, hydrocephalus, and other defects.
