Inherited MC1R variants in patients with melanoma are associated with better survival in women.

Inherited MC1R variants are associated with improved overall survival in women with melanoma but not in men. Intrinsic sex-dependent features can modify the role of specific genes in melanoma prognosis. We believe that survival studies of patients with melanoma should include analysis by sex and MC1R genotype. What's already known about this topic? Inherited MC1R variants have been associated with a better melanoma prognosis, but their interaction with sex is unknown. What does this study add? MC1R variants are related to better overall survival and melanoma-specific survival in women but not in men. What is the translational message? These differences between the sexes could imply future changes in melanoma follow-up and treatment strategies. This provides a basis for understanding the interaction between sex-related genes and germline variants in cancer.
