Genes affected

FARSA (HGNC:3592): (phenylalanyl-tRNA synthetase subunit alpha) Aminoacyl-tRNA synthetases are a class of enzymes that charge tRNAs with their cognate amino acids. This gene encodes a product which is similar to the catalytic subunit of prokaryotic and Saccharomyces cerevisiae phenylalanyl-tRNA synthetases (PheRS). This gene product has been shown to be expressed in a tumor-selective and cell cycle stage- and differentiation-dependent manner, the first member of the tRNA synthetase gene family shown to exhibit this type of regulated expression [provided by RefSeq, Jul 2008]

The c.1018G>C (p.A340P) alteration is located in exon 9 (coding exon 9) of the FARSA gene. This alteration results from a G to C substitution at nucleotide position 1018, causing the alanine (A) at amino acid position 340 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
