CircleDNA's Premium Test includes personalised reports on Melanoma risk. See your cancer genetic risk →

Skin cancer with significant hereditary component. CDKN2A mutations account for 20–40% of familial cases; MC1R variants affect sporadic risk.

How Genetic Is Melanoma?

Melanoma involves complex interactions between multiple genes and environmental factors. Heritability estimates range up to 58%, though no single gene determines outcome on its own.

Key genes associated with Melanoma: CDKN2A MC1R BRAF. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.

Does Family History Matter for Melanoma?

Family history can be informative for Melanoma, but its predictive power is limited because many genes — each with small effects — combine with environmental influences. A family history of the condition may prompt earlier or more frequent screening.
