SOD2 and melanoma: Similar results were also observed in the recessive model, where an 85% reduction in the odds of melanoma (OR 0.15, 95% CI: 0.06, 0.33, p < 0.001) was observed for rs8031 (SOD2) with TT minor alleles, and a 91% reduction (OR 0.09, 95% CI: 0.01, 0.33, p = 0.002 with marginal significance) for rs2536512 (SOD3) with AA minor alleles.
