abstract: Incidence and predictors of positive and negative effects of BRCA1/2 genetic testing on familial relationships: a 3-year follow-up study

"....Reporting positive relationship effects was associated with older age, intolerance for uncertainty, cancer-specific distress, and more social support. Low education, positive attitude toward prophylactic mastectomy, and low social support increased the likelihood of negative effects.

Conclusion:Our findings do not support the belief that family relationships are frequently disrupted by BRCA1/2 testing."
