PMS2 and adenoma: We observed statistically significant differences in the number of adenomas among the different MMR gene carriers (P<0.001) with MSH6 carriers having the most adenomas (0.82; IQR, 0-5; range, 0-5) followed by MSH2/EPCAM (0.61; IQR, 0-5; range, 0-7), PMS2 (0.44; IQR, 0-1; range, 0-2) and MLH1 (0.32; IQR, 0-3; range, 0-4).
