Genes affected

VARS1 (HGNC:12651): (valyl-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. The protein encoded by this gene belongs to class-I aminoacyl-tRNA synthetase family and is located in the class III region of the major histocompatibility complex. [provided by RefSeq, Jul 2008]

The c.3460G>C (p.V1154L) alteration is located in exon 29 (coding exon 28) of the VARS gene. This alteration results from a G to C substitution at nucleotide position 3460, causing the valine (V) at amino acid position 1154 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
