Are Hispanic women second most common group to carry BRCA gene mutations?

Latinas are the second most common ethnic group to carry BRCA1 deleterious mutations, after Ashkenazi Jewish women, among all patients with breast cancer.

However, Latinas are less likely to receive genetic counseling education, referrals, and testing services and have the least awareness of genetic testing compared to non-Hispanic whites and other minority populations. Research indicates that despite their low awareness, Latinas have high interest in participating in genetic counseling and testing. Breast cancer is the most commonly diagnosed cancer and the leading cause of cancer death in Latina women.

BRCA1 (BReast CAncer gene 1) and BRCA2 (BReast CAncer gene 2) are genes that produce proteins that help repair damaged DNA. People who inherit harmful mutations in one of these genes have increased risks of several cancers, most notably breast and ovarian cancer, and tend to develop cancer at younger ages than people who do not have such a mutation.
