Summary

Familial melanoma represents approximately 10% of all melanomas. In patients with hereditary melanoma, the onset of the disease is at a young age (below 40), and the incidence of multiple melanomas is relatively high (30%). The most commonly mutated gene in familial melanoma is the cdkn2a gene (germline mutations in 30–50%), which encodes for two different proteins, P16INK4a and P14ARF, and is a key regulator of the cell cycle. Another high penetrance gene identified in melanoma is cdk4, which is involved in cell cycle progression. However, cdk4 germline mutations are rare and play a minor role in hereditary melanoma.

Some low penetrance genes have been described in melanoma, including DNA repair genes such as ercc1 or xrcc3, and pigmentation genes such as mc1r. While specific variants of the mc1r gene have been associated with an increased risk for melanoma, conflicting data exist on other potential low penetrance genes regarding their role in the susceptibility to melanoma. Genetic testing of familial melanoma patients is generally not recommended.
