Analysis of seven HNPCC-associated hMLH1 missense mutations located within the hMRE11-interacting domain shows that four mutations (L574P, K618T, R659P and A681T) cause near-complete disruption of the interaction between hMRE11 and hMLH1, and two mutations (Q542L and L582V) cause a 30% reduction of protein interaction.

Mutation analysis of the MLH1, MSH2 and MSH6 genes in patients with double primary cancers of the colorectum and the endometrium: a population-based study in northern Sweden.
Molecular analysis of hereditary nonpolyposis colorectal cancer in the United States: high mutation detection rate among clinically selected families and characterization of an American founder genomic deletion of the MSH2 gene.
We recommend a screening strategy for the local LS by starting with tumor IHC and the hotspot mutation testing at MLH1 c.793C>T followed by comprehensive mutation scanning in MLH1 and MSH2 prior to proceeding to other MMR genes.
Evidence from clinical, histological, immunohistochemical, and molecular genetic data suggests that MLH1 c.1664T>C (p.Leu555Pro) is likely to be the pathogenic cause of Lynch syndrome in this family.
