Similarly, this study shows that FTO rs9939609 A allele carriers had an increased risk (odds) of overweight/obesity [OR = 0.19 (95% CI: 0.10, 0.36); p < 0.001], central obesity [OR = 0.33 (95% CI: 0.15, 0.71); p < 0.001], and visceral obesity [OR = 0.12 (95% CI: 0.06, 0.23); p < 0.001] compared with the TT homozygotes. The gene discussed is FTO; the disease is obesity due to melanocortin 4 receptor deficiency.
