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

Our verdict: Benign. The variant received -8 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.45).
• BP6: Variant 1-109214040-A-G is Benign according to our data. Variant chr1-109214040-A-G is described in ClinVar as Likely_benign. ClinVar VariationId is 3057588.Status of the report is no_assertion_criteria_provided, 0 stars.
• BP7: Synonymous conserved (PhyloP=-0.075 with no splicing effect.
• BS1: Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.0000794 (116/1461800) while in subpopulation NFE AF = 0.000103 (115/1111970). AF 95% confidence interval is 0.0000876. There are 1 homozygotes in GnomAdExome4. There are 58 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
