The analysis of MUTYH-associated polyposis cases of the EPIPOLIP cohort confirms the importance of including serrated polyps in the diagnostic work-up of patients with oligopolyposis, suggests a role for screening polyps for the somatic c.34G>T KRAS mutation, and allows the implementation of a genetic testing strategy based on population data.

Colorectal cancer (CRC) is the third most common type of cancer in Switzerland in terms of annual new cases and cancer deaths. Since most cantons have an organized screening program, more people are recorded with a positive family history of CRC. In the majority, the familial form of CRC is present, a hereditary form is much less common.

Background: -associated polyposis is an autosomal recessive disorder associated with an increased lifetime risk of colorectal cancer and a moderately increased risk of ovarian, bladder, breast, and endometrial cancers. We analyzed the carrier frequency and estimated the incidence of -associated polyposis in East Asian and Korean populations, for which limited data were previously available.
Methods: We examined 125,748 exomes from the gnomAD database, including 9,197 East Asians, and additional data from 5,305 individuals in the Korean Variant Archive and 1,722 in the Korean Reference Genome Database.

Variation in DNA repair genes can increase cancer risk by elevating the rate of oncogenic mutation. Defects in one such gene, MUTYH, are known to elevate the incidence of colorectal cancer in a recessive Mendelian manner. Recent evidence has also linked MUTYH to a mutator phenotype affecting normal somatic cells as well as the female germline.
