Mutations in the mismatch repair gene MSH2 underlie hereditary nonpolyposis colorectal cancer (Lynch syndrome). Whereas disruptive mutations are overtly pathogenic, the implications of missense mutations found in sporadic colorectal cancer patients or in suspected Lynch syndrome families are often unknown. Adequate genetic counseling of mutation carriers(More)
Missense variants of DNA mismatch repair (MMR) genes pose a problem in clinical genetics as long as they cannot unambiguously be assigned as the cause of Lynch syndrome (LS). To study such variants of uncertain clinical significance, we have developed a functional assay based on direct measurement of MMR activity in mouse embryonic stem cells expressing(More)
BACKGROUND Lynch syndrome, an autosomal-dominant disorder characterised by high colorectal and endometrial cancer risks, is caused by inherited mutations in DNA mismatch repair (MMR) genes. Mutations fully abrogating gene function are unambiguously disease causing. However, missense mutations often have unknown functional implications, hampering genetic(More)
Lynch syndrome confers an increased risk to various types of cancer, in particular early onset colorectal and endometrial cancer. Mutations in mismatch repair (MMR) genes underlie Lynch syndrome, with the majority of mutations found in MLH1 and MSH2. Mutations in MSH6 have also been found but these do not always cause a clear cancer predisposition phenotype(More)
