Genes affected

TARS1 (HGNC:11572): (threonyl-tRNA synthetase 1) Aminoacyl-tRNA synthetases catalyze the aminoacylation of tRNA by their cognate amino acid. Because of their central role in linking amino acids with nucleotide triplets contained in tRNAs, aminoacyl-tRNA synthetases are thought to be among the first proteins that appeared in evolution. Threonyl-tRNA synthetase belongs to the class-II aminoacyl-tRNA synthetase family [provided by RefSeq, Jul 2008]

The c.131G>A (p.R44Q) alteration is located in exon 2 (coding exon 2) of the TARS gene. This alteration results from a G to A substitution at nucleotide position 131, causing the arginine (R) at amino acid position 44 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
