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]

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.
