Genes affected

RARS1 (HGNC:9870): (arginyl-tRNA synthetase 1) Aminoacyl-tRNA synthetases catalyze the aminoacylation of tRNA by their cognate amino acid. Because of their central role in linking amino acids with nucleotide triplets contained in tRNAs, aminoacyl-tRNA synthetases are thought to be among the first proteins that appeared in evolution. Arginyl-tRNA synthetase belongs to the class-I aminoacyl-tRNA synthetase family. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 5 ACMG points.

PVS1

Start lost variant, next in-frame start position is after 1 pathogenic variants. Next in-frame start position is after 216 CDS bases. Genomic position: 168492694. Lost 0.109 part of the original CDS.

PS1

Another start lost variant in NM_002887.4 (RARS1) was described as [Pathogenic] in Lovd

PP5

Variant 5-168486501-G-T is Pathogenic according to our data. Variant chr5-168486501-G-T is described in ClinVar as [Pathogenic]. Clinvar id is 1218728.Status of the report is criteria_provided_single_submitter, 1 stars.

BS2

High AC in GnomAd4 at 5 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
