UGT1A1 and Hodgkins lymphoma: Finally, higher bilirubin levels predicted by the non-UGT1A1 SNPs were inversely associated with risk of Hodgkin’s lymphoma (OR 0.64, 95% CI 0.42–0.99) (Figure 1D and Figure S5A), while null results were observed for melanoma or neuroblastoma risk (Figure 1D and Figure S5B,C).
