YARS2 - tyrosyl-tRNA synthetase 2 Gene

Homo sapiens

Also known as TYRRS; CGI-04; MLASA2; MT-TYRRS

Gene ID: 51067 | Gene type: protein coding

About YARS2

Cytogenetic location: 12p11.21 Genomic coordinates (GRCh38): 12:32,746,544-32,755,897 (from NCBI)

This gene has 3 transcripts (splice variants), 207 orthologues and is associated with 3 phenotypes. Ubiquitous expression in brain (RPKM 10.0), endometrium (RPKM 8.1) and 25 other tissues.

Summary

This gene encodes a mitochondrial protein that catalyzes the attachment of tyrosine to tRNA(Tyr). Mutations in this gene are associated with myopathy with lactic acidosis and sideroblastic anemia type 2 (MLASA2). [provided by RefSeq, Jan 2011]
