Four hundred two patients (89.3%) had MMR-proficient tumors, and 32 patients (8%) had at least 1 gene mutation: 9 had mutations in high-penetrance CRC genes (5, APC; 1, APC/PMS2; 2, biallelic MUTYH; 1, SMAD4); 13 patients had mutations in high- or moderate-penetrance genes not traditionally associated with CRC (3, ATM; 1, ATM/CHEK2; 2, BRCA1; 4, BRCA2; 1, CDKN2A; 2, PALB2); 10 patients had mutations in low-penetrance CRC genes (3, APC c.3920T>A, p.I1307K; 7, monoallelic MUTYH).

The I1307K mutation is associated with a moderate excess risk for CRC, but age of onset seems not to be earlier and this variant is not associated with a multiple colonic polyp phenotype.

This excess can partially be attributed to inherited factors that are over represented in this population, such as the APC variant I1307K, which is associated with a modest increase in colorectal cancer risk.
