Classic lissencephaly, also known as lissencephaly type I, is a brain malformation that may occur as an isolated abnormality (isolated lissencephaly sequence) or in association with certain underlying syndromes (e.g., Miller-Dieker syndrome, Norman-Roberts syndrome). The condition is characterized by agyria or pachygyria of the gyri of the cerebral cortex, causing the brain's surface to appear unusually smooth. In infants with classic lissencephaly, microcephaly is usually present. Other clinical features include seizures, severe or profound mental retardation, feeding difficulties, growth retardation, and impaired motor functions.
