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]

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]

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.022679478).

Collection Method: clinical testing

The c.1463T>C (p.V488A) alteration is located in exon 14 (coding exon 14) of the AARSD1 gene. This alteration results from a T to C substitution at nucleotide position 1463, causing the valine (V) at amino acid position 488 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
