Intervention Group A: Non-Hispanic White Population

Post determination of MC1R Genotypes, participants randomized to the intervention group, will receive personalized information about ways that they can protect themselves and their child from developing melanoma.

By the end of the study, all participants will have had the opportunity to receive information about their inherited risk.

Intervention Group B: Hispanic Population

Post determination of MC1R Genotypes, participants randomized to the intervention group, will receive personalized information about ways that they can protect themselves and their child from developing melanoma.

By the end of the study, all participants will have had the opportunity to receive information about their inherited risk.

Control Group A: Non-Hispanic White Population

Post determination of MC1R Genotypes, participants randomized to the control group, you will receive standard information about ways that they can protect themselves and their child from developing melanoma.

By the end of the study, all participants will have had the opportunity to receive information about their inherited risk. Participants randomized into the control group, by the end of the study will also have had the opportunity to receive personalized information about ways they can protect themselves and their child from developing melanoma.

Personalized information about ways that participants can protect themselves and their child from developing melanoma.

Personalized Information

Standard information about ways that participants can protect themselves and their child from developing melanoma.

Standard Information

After signing informed consent, a biologic sample (saliva) will be collected for the purpose of DNA extraction determination of MC1R genotypes. All participants who carry high risk MC1R genotypes and a proportion of those who carry low risk or no MC1R variants will be randomized to the control or intervention arm.

DNA Extraction Determination of MC1R Genotypes

Peter Kanetsky, Ph.D

The purpose of this study is to examine how different messages about risk of melanoma can impact the way people protect themselves against developing these diseases.
