Interestingly, we found that both subgroups shared a spectrum of alterations in 13 genes (CYP1B1, CASP8, BAP1, PIK3CA, TERT, CDKAL1, CDKN2A, TYR, POLE, OCA2, TERF2IP, MC1R, MGMT), which suggests that they may have role in the development of melanoma. This evidence concerns the gene CDKAL1 and melanoma.
