ABSTRACT
Introduction: Cutaneous melanoma is a malignancy with complex aetiology that could be considered as a result of interplay between phenotypic characteristics, various environmental exposures and genetic variants.
Areas covered: Several genes have been found to be robustly associated with risk for melanoma. Emerging approaches such as genome-wide association studies have revealed several such postulated genes but most of the identified loci have weak to moderate risk effects, with Odds Ratios ranging, mostly, between 1.10 and 1.40. Ideally, such discoveries could shift research towards precision or individualized medicine on the prevention front and could lead to better individual risk prediction; however current findings have not highlighted adequate number of disease pathways or variants with large effect sizes and population attributable risk.
Expert commentary: The potential impact of larger studies and big data to improve health, prevent and detect melanoma at an earlier stage and personalize interventions could be tremendous in the near future.
