RARS1 p.Asp2Gly

Variant summary

Our verdict is Pathogenic. The variant received 13 ACMG points: 14P and 1B. PS3PM2PP5_Very_StrongBP4

The NM_002887.4(RARS1):​c.5A>G​(p.Asp2Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000282 in 1,558,898 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV001132579: Functional studies have shown that this variant causes severely reduced function of the protein complex (Nafisinia et al. 2017, PMID:28905880" and additional evidence is available in ClinVar. Synonymous variant affecting the same amino acid position (i.e. D2D) has been classified as Likely benign.

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 was made for transcript

Our verdict: Pathogenic. The variant received 13 ACMG points.

PS3
PS3 evidence extracted from ClinVar submissions: SCV001132579: Functional studies have shown that this variant causes severely reduced function of the protein complex (Nafisinia et al. 2017, PMID: 28905880; Wolf et al. 2014, PMID: 24777941).
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 5-168486503-A-G is Pathogenic according to our data. Variant chr5-168486503-A-G is described in ClinVar as Pathogenic. ClinVar VariationId is 162080.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP4
Computational evidence support a benign effect (MetaRNN=0.30144027). . Strength limited to SUPPORTING due to the PP5.
