Genes affected

MSRA (HGNC:7377): (methionine sulfoxide reductase A) This gene encodes a ubiquitous and highly conserved protein that carries out the enzymatic reduction of methionine sulfoxide to methionine. Human and animal studies have shown the highest levels of expression in kidney and nervous tissue. The protein functions in the repair of oxidatively damaged proteins to restore biological activity. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2014]

The c.62C>G (p.P21R) alteration is located in exon 1 (coding exon 1) of the MSRA gene. This alteration results from a C to G substitution at nucleotide position 62, causing the proline (P) at amino acid position 21 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
