BRCA1 and BRCA2 mutations across race and ethnicity: distribution and clinical implications CURRENT OPINION IN OBSTETRICS & GYNECOLOGY Kurian, A. W. 2010; 22 (1): 72-78

Abstract

To summarize evidence on the prevalence and spectrum of BRCA1 and BRCA2 BRCA1/2 mutations across racial and ethnic groups and discuss implications for clinical practice.The prevalence of BRCA1/2 mutations is comparable among breast cancer patients of African, Asian, white, and Hispanic descent: approximately 1-4% per gene. Among ovarian cancer patients in North America, BRCA1/2 mutations are present in 13-15%. Between racial/ethnic groups, there are important differences in the spectrum of BRCA1 compared with BRCA2 mutations, in BRCA1/2 variants of uncertain significance, and in the accuracy of clinical models that predict BRCA1/2 mutation carriage.Given the significant prevalence of BRCA1/2 mutations across race/ethnicity, there is a need to expand and customize genetic counseling, genetic testing, and follow-up care for members of all racial/ethnic groups.
