OMIM® : ⁵⁷ Hypomyelinating leukodystrophy-12 is an autosomal recessive neurologic disorder characterized by severely delayed or even lack of psychomotor development that becomes apparent in the first months of life. Patients are markedly disabled, with acquired microcephaly, lack of speech, and often lack of spontaneous movement due to hypotonia and spasticity. Brain imaging shows delayed myelination (summary by Edvardson et al., 2015). For a general phenotypic description and a discussion of genetic heterogeneity of HLD, see 312080.

MalaCards based summary : Leukodystrophy, Hypomyelinating, 12, also known as hld12, is related to pelizaeus-merzbacher disease and autosomal recessive disease. An important gene associated with Leukodystrophy, Hypomyelinating, 12 is VPS11 (VPS11 Core Subunit Of CORVET And HOPS Complexes), and among its related pathways/superpathways are Salmonella infection (KEGG) and Amoebiasis. Related phenotypes are intellectual disability and global developmental delay

Disease Ontology : ¹² A hypomyelinating leukodystrophy characterized by autosomal recessive inheritance of severely delayed or even lack of psychomotor development that becomes apparent in the first months of life, acquired microcephaly and delayed myelination that has material basis in homozygous mutation in the VPS11 gene on chromosome 11q23.

UniProtKB/Swiss-Prot : ⁷³ Leukodystrophy, hypomyelinating, 12: An autosomal recessive neurologic disorder characterized by developmental delay, spasticity, truncal hypotonia, acquired microcephaly, intellectual disability with variable seizure disorder, accompanied by thin corpus callosum, paucity of white matter and delayed myelination.
