ABCG2 and gout: ABCG2 SNP (rs2231142) significantly increased the risk of gout in Asians (dominant model: OR = 2.64, 95% CI = 2.04–3.43, p = 0.02 for heterogeneity; recessive model: OR = 3.19, 95% CI = 2.56–3.97, p = 0.28 for heterogeneity; co-dominant model: OR = 1.37, 95% CI = 1.18–1.59, p = 0.09 for heterogeneity) as well as other populations (dominant model: OR = 1.85, 95% CI = 1.20–2.85, p < 0.0001 for heterogeneity; recessive model: OR = 3.78, 95% CI = 2.28–6.27, p = 0.19 for heterogeneity; co-dominant model: OR = 1.48, 95% CI = 1.26–1.74, p = 0.19 for heterogeneity) (Li et al., 2015a).
