Our analysis revealed that FTO rs9939609 had a certain correlation with an elevated cancer risk within the Asian demographic q vs. r (OR = 1.22, 95% CI = 1.07–1.39, p = 0.003); rq + qq vs. rr (OR = 1.18, 95% CI = 1.04–1.35, p = 0.011); qq vs. rr + rq (OR = 1.78, 95% CI = 1.39–2.27, p = 0.001). This evidence concerns the gene FTO and cancer.
