Overview

Microhydranencephaly (MHAC) is a severe abnormality of brain development characterized by both microcephaly and hydranencephaly. Signs and symptoms may include severe microcephaly, scalp rugae (a series of ridges), and profound developmental delay.[1] Familial occurrence of the condition is very rare but it has been reported in a few families. It has been suggested that MHAC is possibly inherited in an autosomal recessive manner.[1][2]
