A gene important in skin tanning has been linked to higher risk for testicular cancer in white men, according to a study led by scientists from the U.S. National Institutes of Health and the University of Oxford in England. Nearly 80 percent of white men carry a variant form of this gene, which increased risk of testicular cancer up to threefold in the study.

I wonder if peptides like Melanotan upregulate this gene.
