FAP and colorectal carcinoma: Interestingly, FAP P can be distinguished from FAP and FIT + NM tissues by a positive correlation between the Wnt/β-catenin molecular markers, nuclear β-catenin, AXIN2 and cMYC, and FAP-faecal Clostridium_sensu_stricto_1, which is one of the main intestinal genera reported in the literature to be positively associated with CRC [28, 29].
