Familial Schizencephaly

Abstract
Familial cases of schizencephaly hitherto have been associated with readily diagnosable metabolic conditions or malformation syndromes. Where such associations are absent, it is usually considered to be a sporadic event without a genetic contribution. Described here are a brother and sister with identical bilateral symmetrical schizencephaly. Genetic counselling must therefore allow for the possibility of an autosomal recessive form of this condition.
