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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 04, 2024The c.1057A>G (p.I353V) alteration is located in exon 10 (coding exon 10) of the FARSA gene. This alteration results from a A to G substitution at nucleotide position 1057, causing the isoleucine (I) at amino acid position 353 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
