Description

The p.L758V variant (also known as c.2272C>G), located in coding exon 4 of the MSH6 gene, results from a C to G substitution at nucleotide position 2272. The leucine at codon 758 is replaced by valine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
