VARS2 - valyl-tRNA synthetase 2, mitochondrial Gene
Also Known as VALRS; VARSL; VARS2L; COXPD20
Species: Homo sapiens
About VARS2
This gene has 13 transcripts (splice variants), 1 gene allele, 180 orthologues, 7 paralogues and is associated with 1 phenotype. Ubiquitous expression in brain (RPKM 7.4), esophagus (RPKM 6.1) and 25 other tissues.
Summary
This gene encodes a mitochondrial Aminoacyl-tRNA Synthetase, which catalyzes the attachment of valine to tRNA(Val) for mitochondrial translation. Mutations in this gene cause combined Oxidative Phosphorylation deficiency-20, and are also associated with early-onset mitochondrial encephalopathies. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Aug 2014]
