Megalencephaly-polymicrogyria-polydactyly-hydrocephalus Syndrome 3; Mpph3

Description

This disorder comprises macrocephaly, megalencephaly, ventriculomegaly, polymicrogyria, and polydactyly. Most affected individuals have severely delayed psychomotor development (summary by Mirzaa et al., 2014).For a discussion of genetic heterogeneity of MPPH, see MPPH1 (OMIM ).
