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 4 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.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.827

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 13, 2024The c.547G>A (p.E183K) alteration is located in exon 5 (coding exon 5) of the SARS gene. This alteration results from a G to A substitution at nucleotide position 547, causing the glutamic acid (E) at amino acid position 183 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
