Genes affected
LARS2 (HGNC:17095): (leucyl-tRNA synthetase 2, mitochondrial) This gene encodes a class 1 aminoacyl-tRNA synthetase, mitochondrial leucyl-tRNA synthetase. Each of the twenty aminoacyl-tRNA synthetases catalyzes the aminoacylation of a specific tRNA or tRNA isoaccepting family with the cognate amino acid. [provided by RefSeq, Jul 2008]
LARS2-AS1 (HGNC:40796): (LARS2 antisense RNA 1)
