Invitae RCV000556059 SCV000624731 uncertain significance Hereditary nonpolyposis colon cancer 2018-12-28 criteria provided, single submitter clinical testing This sequence change replaces isoleucine with methionine at codon 725 of the MSH6 protein (p.Ile725Met). The isoleucine residue is weakly conserved and there is a small physicochemical difference between isoleucine and methionine. This variant is present in population databases (rs63750304, ExAC 0.005%). This variant has been reported in an individual affected with colorectal cancer (PMID: 11709755). ClinVar contains an entry for this variant (Variation ID: 89257). An algorithm developed specifically for the MSH6 gene (PMID: 22290698, 23621914), suggests that this missense change is likely to be tolerated. However, this prediction has not been confirmed by published functional studies and its clinical significance is uncertain. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
