Genes affected

EPRS1 (HGNC:3418): (glutamyl-prolyl-tRNA synthetase 1) Aminoacyl-tRNA synthetases are a class of enzymes that charge tRNAs with their cognate amino acids. The protein encoded by this gene is a multifunctional aminoacyl-tRNA synthetase that catalyzes the aminoacylation of glutamic acid and proline tRNA species. Alternative splicing has been observed for this gene, but the full-length nature and biological validity of the variant have not been determined. [provided by RefSeq, Jul 2008]

The c.4519T>A (p.L1507I) alteration is located in exon 32 (coding exon 32) of the EPRS gene. This alteration results from a T to A substitution at nucleotide position 4519, causing the leucine (L) at amino acid position 1507 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
