But neither the UCP2 Ala55Val nor the UCP3 -55C/T polymorphism showed any significant association with obesity risk in either subjects of Asian (REM OR = 0.84, 95% CI: 0.67–1.06 for Ala55Val; REM OR = 0.94, 95% CI: 0.55–1.28 for -55C/T) or of European descent (REM OR = 1.04, 95% CI: 0.80-1.36 for Ala55Val; FEM OR = 1.08, 95% CI: 0.97–1.20 for -55C/T). The gene discussed is UCP2; the disease is obesity disorder.
