Familial Alobar Holoprosencephaly
📋Overview
Familial Alobar Holoprosencephaly refers to a severe form of holoprosencephaly, a congenital brain malformation characterized by incomplete division of the forebrain (prosencephalon) into two hemispheres. The term 'familial' indicates a hereditary pattern, often involving genetic mutations affecting early brain development. Alobar holoprosencephaly is the most severe subtype, with a single brain ventricle and fused cerebral hemispheres. Modern terminology focuses on holoprosencephaly with specification of severity rather than the legacy term alone.
