J Conclusion The postulated high frequency and continent-wide geographic distribution of a cancer-predisposing founder mutation of the MSH2 gene in a large, outbred (as opposed to genetically isolated) population, and the ease with which the mutation can be detected, suggest that the routine testing of individuals at risk for HNPCC in the United States should include an assay for this mutation until more is learned about its occurrence. MSH2. mutations. The National Comprehensive Cancer Network (NCCN) provides risk management guidelines for men and women with MSH2 mutations.
