Summaries for Leukodystrophy, Hypomyelinating, 10

OMIM : ⁵⁷ Hypomyelinating leukodystrophy-10 is an autosomal recessive neurologic disorder characterized by postnatal progressive microcephaly, severely delayed psychomotor development, and hypomyelination on brain imaging (summary by Nakayama et al., 2015). For a general phenotypic description and a discussion of genetic heterogeneity of HLD, see 312080. (616420)

MalaCards based summary : Leukodystrophy, Hypomyelinating, 10, is also known as hld10. An important gene associated with Leukodystrophy, Hypomyelinating, 10 is PYCR2 (Pyrroline-5-Carboxylate Reductase 2), and among its related pathways/superpathways are Viral mRNA Translation and Amino acid synthesis and interconversion (transamination). Affiliated tissues include brain, eye and skeletal muscle, and related phenotypes are malar flattening and low-set ears

Disease Ontology : ¹² A hypomyelinating leukodystrophy characterized by autosomal recessive inheritance of progressive postnatal microcephaly, severely delayed psychomotor development and hypomyelination that has material basis in homozygous mutation in the PYCR2 gene on chromosome 1q42.

UniProtKB/Swiss-Prot : ⁷⁵ Leukodystrophy, hypomyelinating, 10: An autosomal recessive neurologic disorder characterized by postnatal microcephaly, severely delayed psychomotor development, hypomyelination, and reduced cerebral white-matter volume.
