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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2022The c.23C>T (p.A8V) alteration is located in exon 1 (coding exon 1) of the MSRA gene. This alteration results from a C to T substitution at nucleotide position 23, causing the alanine (A) at amino acid position 8 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
