Two associations [26,70] were graded as highly credible within the Asian population for type 2 diabetes (Table 2): rs1024611 at MCP-1 gene was linked to a higher risk of DR under the dominant model (GG+GA vs. AA), and rs3025039 at VEGF gene was associated with an increased risk of PDR under the homozygous model (TT vs. CC). The gene discussed is CCL2; the disease is type 2 diabetes mellitus.
