Familial Dandy-Walker syndrome: a case report supporting an autosomal inheritance.

INTRODUCTION: We report an isolated pedigree in which a consanguineous couple had twin sons with Dandy-Walker malformation (DWM). The mother is similarly affected with the disorder. DISCUSSION: DWM is an abnormality of the central nervous system, which leads to hydrocephalus and is associated with other abnormalities. CONCLUSION: Inheritance of the disorder remains controversial, with the majority perceived to be sporadic cases. This report suggests an autosomal inheritance.
