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 Uncertain_significance. Variant got 2 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SARS1. . Gene score misZ 2.6571 (greater than the threshold 3.09). Trascript score misZ 3.2534 (greater than threshold 3.09). GenCC has associacion of gene with autosomal recessive non-syndromic intellectual disability, neurodevelopmental disorder with microcephaly, ataxia, and seizures.

BP4

Computational evidence support a benign effect (MetaRNN=0.34970224).

The c.155A>G (p.N52S) alteration is located in exon 2 (coding exon 2) of the SARS gene. This alteration results from a A to G substitution at nucleotide position 155, causing the asparagine (N) at amino acid position 52 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
