Genes affected
SARS1 (HGNC:10537): (seryl-tRNA synthetase 1) This gene belongs to the class II amino-acyl tRNA family. The encoded enzyme catalyzes the transfer of L-serine to tRNA (Ser) and is related to bacterial and yeast counterparts. Multiple alternatively spliced transcript variants have been described but the biological validity of all variants is unknown. [provided by RefSeq, Jul 2010]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (MetaRNN=0.045895845).
BS1
Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0000788 (12/152340) while in subpopulation AMR AF= 0.000523 (8/15306). AF 95% confidence interval is 0.00026. There are 0 homozygotes in gnomad4. There are 6 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Collection Method: clinical testing

The c.355G>A (p.A119T) alteration is located in exon 4 (coding exon 4) of the SARS gene. This alteration results from a G to A substitution at nucleotide position 355, causing the alanine (A) at amino acid position 119 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
