Description

The p.K59R variant (also known as c.176A>G), located in coding exon 1 of the MSH2 gene, results from an A to G substitution at nucleotide position 176. The lysine at codon 59 is replaced by arginine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
