Abstract

About 10% of melanoma cases have clinical factors indicative of hereditary cancer. CDKN2A is a major melanoma susceptibility gene in familial malignant melanoma. In this study a novel L94Q missense mutation of the CDKN2A gene is described in a melanoma kindred with two affected second-degree family members. To detect the mutation, polymerase chain reaction (PCR) amplification methods and direct sequencing were used. The presence of the mutation was confirmed by restriction fragment length polymorphism analysis after digestion of the PCR amplicons with the restriction endonuclease BspMI. The penetrance of the novel mutation was shown to be incomplete. Functional importance of the mutation was assumed from the protein p16 structure.
