Association of low-risk MSH3 and MSH2 variant alleles with Lynch syndrome: probability of synergistic effects.

Abstract excerpt

Mutations in the MLH1 and MSH2 genes account for a majority of cases of families with Lynch Syndrome. Germ-line mutations in MSH6, PMS2 and MLH3 are responsible for disease in a minority of cases, usually associated with milder and variable phenotypes. No germ-line mutations in MSH3 have so far been associated with Lynch Syndrome, although it is known that impaired MSH3 activity leads to a partial defect in...
