title: Hereditary cutaneous melanoma.
abstract: Members of some kindreds have a hereditary predisposition for development of cutaneous melanoma. Cytogenetic and linkage studies implicated chromosomes 1p and 9p as possible locations for genetic alterations predisposing for melanoma. Germline mutations in the CDKN2A gene on chromosome 9p21 have been identified in hereditary melanoma, but are present in only approximately 40% of kindreds with linkage to 9p21, indicating that changes in other gene(s) at this location may also predispose to melanoma. In a few families, germline mutations in the CDK4 gene are present. The genetic alterations underlying disease predisposition in a large proportion of melanoma families remain unknown.
