UGT1A1 and renal cell adenocarcinoma: Neither the UGT1A1 SNP nor the non-UGT1A1 SNPs were associated with risk of renal cell cancer in men and women combined (Figure 1A and Figure S1D–F); however, a suggestive inverse association was observed between bilirubin levels predicted by the non-UGT1A1 SNPs and renal cell cancer in men (OR 0.76; 95% CI 0.57–1.00).
