CDKN2A and melanoma: Individuals at increased risk of melanoma include those carrying germline alleles of common genetic variants of pigment‐related genes such as MC1R [4, 5, 6], whereas high penetrance variants affecting genes such as those that regulate telomere length and stability (TERT, POT1) and cell cycle control/senescence (CDKN2A, CDK4) have also been implicated [7, 8, 9, 10, 11].
