Leukodystrophy, Hypomyelinating, 3; Hld3

Description

Autosomal recessive hypomyelinating leukodystrophy-3 (HLD3) is a severe neurologic disorder characterized by early infantile onset of global developmental delay, lack of development, lack of speech acquisition, and peripheral spasticity associated with decreased myelination in the central nervous system (summary by Feinstein et al., 2010).The disorder is phenotypically similar to X-linked Pelizaeus-Merzbacher disease (PMD ), which is caused by mutation in the PLP1 gene (OMIM ). For a general phenotypic description and a discussion of genetic heterogeneity of HLD, see {312080}.
