The melanocortin 1 receptor gene is a main determinant of human pigmentation, and a melanoma susceptibility gene, because its variants that are strongly associated with red hair color increase melanoma risk. To test experimentally the association between melanocortin 1 receptor genotype and melanoma susceptibility, we compared the responses of primary human(More)
PURPOSE Genetic testing of minors is controversial, as ethical considerations depend on multiple aspects of the particular disease and familial context. For melanoma, there is a well-established and avoidable environmental influence and a documented benefit of early detection. METHODS We surveyed 61 CDKN2A/p16 mutation-tested adults from two kindreds(More)
Approximately 5% to 10% of melanoma may be hereditary in nature, and about 2% of melanoma can be specifically attributed to pathogenic germline mutations in cyclin-dependent kinase inhibitor 2A (CDKN2A). To appropriately identify the small proportion of patients who benefit most from referral to a genetics specialist for consideration of genetic testing for(More)
We report the results of an association study of melanoma that is based on the genome-wide imputation of the genotypes of 1,353 cases and 3,566 controls of European origin conducted by the GenoMEL consortium. This revealed an association between several SNPs in intron 8 of the FTO gene, including rs16953002, which replicated using 12,313 cases and 55,667(More)
Mutations or deletions in the cyclin-dependent kinase inhibitor p16(INK4A) are associated with multiple cancer types, but are more commonly found in melanoma tumors and associated with familial melanoma predisposition. Although p16 is thought to function as a tumor suppressor by negatively regulating the cell cycle, it remains unclear why the genetic(More)
Only two genome-wide association (GWA) screens have been published for melanoma (Nat Genet 47:920–925, 2009; Nat Genet 40:838–840, 2008). Using a unique approach, we performed a genome-wide association study in 156 related melanoma cases from 34 high-risk Utah pedigrees. Genome-wide association analysis was performed on nearly 500,000 markers; we compared(More)
Epidermal melanocytes are particularly vulnerable to oxidative stress owing to the pro-oxidant state generated during melanin synthesis, and to the intrinsic antioxidant defenses that are compromised in pathologic conditions. Melanoma is thought to be oxidative stress driven, and melanocyte death in vitiligo is thought to be instigated by a highly(More)
Background: A major goal of predictive genetic testing for melanoma is to promote early detection to reduce mortality. This study evaluated the long-term impact of melanoma genetic test reporting and counseling on screening adherence. Methods: This study assessed adherence to recommendations for annual total body skin examinations (TBSE) and monthly skin(More)
OBJECTIVE CDKN2A/p16 mutations confer 76% lifetime risk of melanoma and up to 17% lifetime risk of pancreatic cancer. Our objective was to determine the short- and long-term impact of CDKN2A/p16 genetic counseling and test reporting on psychological distress, cancer worry, and perceived costs and benefits of testing. METHODS Prospective changes in(More)
PURPOSE Reducing ultraviolet radiation exposure may decrease melanoma risk in the hereditary melanoma setting. It is unknown whether genetic counseling and test reporting of CDKN2A/p16 mutation status promote long-term compliance with photoprotection recommendations, especially in unaffected mutation carriers. METHODS This study evaluated changes 2 years(More)
