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]

Collection Method: clinical testing

The 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. -
