VDR and renal cell carcinoma: No associations with VDR or RXRA genotypes were observed with occupational UV exposure and RCC risk among male participants previously observed to have lower RCC risk with increasing occupational sunlight exposure [18]; however, when VDR haplotypes were examined male subjects in the highest cumulative occupational UV exposure category with the A-G-C VDR haplotype had a significant increase in RCC risk compared to male subjects with the referent G-A-T haplotype.
