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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP3

MetaRNN computational evidence supports a deleterious effect, 0.9

BS1

Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.000065 (95/1461804) while in subpopulation NFE AF= 0.0000746 (83/1111970).

The c.4528C>T (p.R1510C) alteration is located in exon 32 (coding exon 32) of the EPRS gene. This alteration results from a C to T substitution at nucleotide position 4528, causing the arginine (R) at amino acid position 1510 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 1510 of the EPRS protein (p.Arg1510Cys). This variant is present in population databases (rs547115453, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with EPRS-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
