Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In collaboration with members of The International Melanoma Consortium, we propose to study melanoma in families lacking mutations in the cyclin-dependent kinase inhibitor 2 (CDKN2 or p16) gene, or the cyclin-dependant kinase 4 (CDK4). CDKN2 and CDK4 are both genes that encode presumed tumor suppressor genes, mutant forms of which are known to cause increased susceptibility to melanoma. The purpose of the present study then is to confirm the existence of and to identify additional gene(s) involved in heritable melanoma (cutaneous and ocular) and their precursor lesions (atypical nevi) by linkage analysis and gene mapping strategies. It is clear that the risk to develop atypical nevi and/or melanoma is strongly influenced by genetic and environmental factors (e.g. sun exposure). Characterization of such genes could provide important insights into the inheritance, pathogenesis, and treatment of this increasingly important disease.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

Inclusion into this study was restricted to families containing at least three CMM cases with DNA available for genotyping, and CDKN2A and CDK4 involvement and had been excluded.

All families must be mutation negative for both CDKN2A and CDK4.

This study will also include families with at least one case of ocular and two cases of other cutaneous melanomas, or at least 2 ocular melanomas (except where they occur in parent and child).

Exclusion Criteria

Any family showing evidence of haplotype sharing in the 9p21-p22 region, where CDKN2A is located, was also excluded.
Eligible Sex
