About this section


Fully expand this MalaCard
Genetics Home Reference:21 Pol III-related leukodystrophy is a disorder that affects the nervous system and other parts of the body. Leukodystrophies are conditions that involve abnormalities of the nervous system's white matter, which consists of nerve fibers covered by a fatty substance called myelin. Myelin insulates nerve fibers and promotes the rapid transmission of nerve impulses.

MalaCards based summary: Pol Iii-Related Leukodystrophies, also known as dentoleukoencephalopathy, is related to leukodystrophy and leukodystrophy with oligodontia, and has symptoms including anomalies of teeth and dentition, late puberty/hypogonadism/hypogenitalism and ataxia/incoordination/trouble of the equilibrium. An important gene associated with Pol Iii-Related Leukodystrophies is POLR3A (polymerase (RNA) III (DNA directed) polypeptide A, 155kDa), and among its related pathways are RNA Polymerase I Promoter Opening and Gene Expression. The drugs selegiline and selegiline hydrochloride and the compounds Thymidine 5'-triphosphate and Adenosine triphosphate have been mentioned in the context of this disorder. Affiliated tissues include brain.
