  • Title: Genetics of melanoma susceptibility.
    Author: Ghiorzo P, Scarrà GB.
    Journal: Forum (Genova); 2003; 13(2):114-22; quiz 187. PubMed ID: 14732879.
    Abstract:
    Both genetic and environmental factors confer a significantly increased risk for cutaneous melanoma. This review discusses hereditary predisposition to the disease, focusing on the high-penetrance candidate genes INK4A/ARF and CDK4, and on pathogenetic mechanisms of mutations in those genes. As known mutations account for approximately 25 to 40% of melanoma families reported to date, it is clear that other melanoma genes and other mechanisms underlying predisposition remain to be discovered. Low penetrance susceptibility genes such as melanocortin 1 receptor and their modifying effect, also in concert with UV radiation, are likely to be implicated. Recent reports on a new candidate locus on chromosome 1p22 and somatic mutations in genes of the RAS-RAF-ERK signalling pathway raise interesting questions for further investigation.
