Clinical Comment
Form of lissencephaly, heterogeneous group of cortical malformations without severe congenital microcephaly, cerebellar underdevelopment from vermian hypoplasia to total aplasia with classical or cobblestone lissencephaly; phenotypic features: small head circumference (birth, postnatally), moderate to severe intellectual disability, hypotonia, spasticity. Seizures often, infantile spasms in rare cases. 6 subgroups according to neuroradiographic properties
