BACKGROUND/AIM: Genetic variations of the CDKN2A and CDK4 gene have been associated to melanoma development. In the present study we investigated the potential associations of CDKN2A and CDK4 gene variants in a colombian population diagnosed with melanoma.
MATERIALS AND METHODS: DNA was extracted from whole blood samples from 85 patients diagnosed with cutaneous melanoma and 166 healthy controls. CDKN2A and CDK4 genes were genotyped using a high-resolution melting assay.
RESULTS: A similar distribution of CDKN2A variants 500C>G and 540C>T was found among cases (12% and 31% respectively) and controls (15% and 31% respectively). The CDKN2A variants were present in 36% of acral lentiginous melanoma and 39.47% of lentigo maligna. The haplotype analysis showed an association with susceptibility in the development of melanoma.
CONCLUSION: The presence of haplotype 500G/540C in males is associated with an increased risk of melanoma in a colombian population, especially in subjects with a family history of cancer.
