DARS2 - aspartyl-tRNA synthetase 2, mitochondrial Gene

Homo sapiens

Also known as LBSL; ASPRS; mtAspRS; MT-ASPRS

Gene ID: 55157 | Gene type: protein coding

About DARS2

Cytogenetic location: 1q25.1 Genomic coordinates (GRCh38): 1:173,824,673-173,858,546 (from NCBI)

This gene has 13 transcripts (splice variants), 214 orthologues, 4 paralogues and is associated with 3 phenotypes. Ubiquitous expression in kidney (RPKM 7.7), colon (RPKM 6.8) and 25 other tissues.

Summary

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]
