Description

The p.N385K variant (also known as c.1155C>G), located in coding exon 7 of the MSH3 gene, results from a C to G substitution at nucleotide position 1155. The asparagine at codon 385 is replaced by lysine, an amino acid with similar properties. This amino acid position is poorly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
