There are also genetically transmitted familial syndromes with alterations in the CDKN2A gene, which encodes for the tumor-suppressing proteins p16 and p19.
Chromosome 9p has been identified as being involved in familial predisposition.

Factors that create a predisposition to malignant melanoma include a family history of the disease, having fair skin that burns easily, a history of excessive sun exposure or sunburns, having numerous moles or atypical moles, and a weakened immune system. Additionally, individuals with a personal history of melanoma or other types of skin cancer are also at an increased risk.
A positive family history of one or two first-degree relatives having had melanoma substantially increases the risk on a genetic basis. A family tendency is observed in 8% to 12% of patients.
Malignant melanoma may develop anywhere on the body.

Malignant melanoma arises in the Stratum basale layer of the epidermal layer.
is malignant melanoma dominant or recessive
Malignant degeneration of the melanocyte gives rise to the tumor known as melanoma, which has four subtypes.
Malignant melanoma is locally staged based on the depth of penetration through the skin and its appendages.

There is also a special type of metastasis that can occur regionally with malignant melanoma; it is known as an in-transit metastasis.
