PURPOSE: Underutilization of genetic testing among Hispanic males results in higher rates of variants of uncertain significance (VUS). We examined the impact of VUS on decision making and behavioral intentions.
METHODS: We conducted a nationwide survey of 807 US Hispanic males aged ≥40 in English and Spanish on perspectives about genetic testing results. Logistic regression was used to examine predictors of worry and behavior change with a hypothetical VUS result.
RESULTS: Over half of Hispanic male participants would still participate in genetic testing with a 1 in 5 chance of VUS. However, 36% were at least somewhat likely to regret testing and 49.9% would worry about cancer risk with VUS results. In addition, 56.3% were somewhat or very likely to change behavior due to a VUS, such as getting checked by the doctor more often or telling family members to get checked. Younger age and college education were associated with more worry and intended behavior change.
CONCLUSION: Although many Hispanic males are interested in genetic testing despite the higher likelihood of VUS, potential consequences include decisional regret, anxiety, and even changes in behavior. Effective counseling and support are important for minoritized groups undergoing genetic evaluation to avoid the potential to exacerbate health disparities.
