PTCSC3 and colonic neoplasm: For PTCSC3 rs944289, the dominant and additive model revealed suggestive associations in the rectal vs. colon comparison (p = 0.043, unadjusted OR = 0.20, 95% CI: 0.04–0.95 and p = 0.048, unadjusted OR = 0.30, 95% CI: 0.09–0.99, respectively) (Table 10), with the minor allele being more frequent in colon tumors.
