Summaries for DARS2 Gene

Entrez Gene Summary for DARS2 Gene

  • The protein encoded by this gene belongs to the class-II aminoacyl-tRNA synthetase family. It is a mitochondrial enzyme that specifically aminoacylates aspartyl-tRNA. Mutations in this gene are associated with leukoencephalopathy with brainstem and spinal cord involvement and lactate elevation (LBSL). [provided by RefSeq, Nov 2009]

GeneCards Summary for DARS2 Gene

DARS2 (Aspartyl-TRNA Synthetase 2, Mitochondrial) is a Protein Coding gene. Diseases associated with DARS2 include leukoencephalopathy with brain stem and spinal cord involvement and lactate elevation and leukoencephalopathy with brain stem and spinal cord involvement - high lactate. Among its related pathways are Gene Expression and tRNA Aminoacylation. GO annotations related to this gene include protein homodimerization activity and aspartate-tRNA ligase activity.

  • Leukoencephalopathy with brainstem and spinal cord involvement and lactate elevation (LBSL) [MIM:611105]: Autosomal recessive disease and is defined on the basis of a highly characteristic constellation of abnormalities observed by magnetic resonance imaging and spectroscopy. Affected individuals develop slowly progressive cerebellar ataxia, spasticity, and dorsal column dysfunction, sometimes with a mild cognitive deficit or decline. {ECO:0000269 PubMed:17384640}. Note=The disease is caused by mutations affecting the gene represented in this entry.
