Melanoma genetic testing to promote reductions in tanning: Results from the Utah BRIGHT project.

1582Background: Predictive genetic testing for familial cancer may alert people to highly elevated risk prior to disease onset. Genetic test reporting has been shown to improve uptake of prophylactic screening and procedures, but whether test reporting also promotes increased performance of primary preventive behavior is unknown. Methods: Unaffected adult participants (N= 124) from high-risk melanoma families, ages 16-69 (mean = 35.24, 52% men) were enrolled. Participants from families that carried a CDKN2A/p16 mutation received a personal genetic test result and counseling about management recommendations whereas control participants from families without a CDKN2A/16 mutation received equivalent counseling and management recommendations based on family history alone. Photoprotection outcomes were compared between CDKN2A/p16 participants (31 carriers, 44 noncarriers) and the no-test control group (n= 49), allowing the effects of receiving a genetic test result to be distinguished from the effects of couns...
