BRAF and colorectal carcinoma: Moreover, gut microbiota analysis in pairwise comparisons between healthy and CRC subjects, revealed that Prevotella intermedia (2.15% vs 0.005%) and Sutterella megalosphaeroides (0.13% vs 0.03%) were enriched in BRAF-mutated cases (FDR = 0.2 and FDR = 0.2, Mann-Whitney test), whereas higher abundance of Clostridium hiranois was retrieved in BRAF wt CRCs (0.4% vs 0.0004%; FDR = 0.01).
