Genes affected

AARSD1 (HGNC:28417): (alanyl-tRNA synthetase domain containing 1) Predicted to enable Ser-tRNA(Ala) hydrolase activity. Predicted to be involved in regulation of translational fidelity. Located in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

AARSD1 links:

PTGES3L-AARSD1 (HGNC:43946): (PTGES3L-AARSD1 readthrough) This locus represents naturally occurring readthrough transcription between the neighboring PTGES3L (prostaglandin E synthase 3 (cytosolic)-like) and AARSD1(alanyl-tRNA synthetase domain containing 1) genes on chromosome 17. The readthrough transcript encodes a fusion protein that shares sequence identity with each individual gene product. [provided by RefSeq, May 2012]

Collection Method: clinical testing

The c.1484G>T (p.G495V) alteration is located in exon 15 (coding exon 15) of the AARSD1 gene. This alteration results from a G to T substitution at nucleotide position 1484, causing the glycine (G) at amino acid position 495 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
