Description

The p.I685M variant (also known as c.2055A>G), located in coding exon 13 of the MSH2 gene, results from an A to G substitution at nucleotide position 2055. The isoleucine at codon 685 is replaced by methionine, an amino acid with highly similar properties. This alteration was identified in a Chinese hereditary breast cancer family (Dong L et al. Cancer Biol Med, 2021 Sep;19:850-70). This amino acid position is not well 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.
