We have investigated the frequency and spectrum of CDKN2A/CDK4 mutations in 23 cutaneous melanoma families from Central Italy (Tuscany). Three distinct mutations were identified in five families. One mutation, p.G23S, was present in three families. Several lines of evidence indicate that p.G23S is a pathogenic mutation: it is located in the functionally important first ankyrinic domain of p16, it was not detected in a sample of 100 control individuals, and it was present in all tested affected individuals from the three families. Haplotype analysis showed a common ancestral origin of the p.G23S mutation. Our data show that the p.G23S mutation is an important cause of hereditary melanoma in Tuscany.
