Varying prevalence among ethnic groups of gene mutation that increases risk of breast cancer

Among several US racial/ethnic groups examined, Hispanic women were found to have the highest prevalence of the cancer-associated gene mutation BRCA1 at 3.5 percent, with Asian Americans having the lowest prevalence (0.5 percent), according to a study in the Dec. 26 issue of JAMA.

1. BRCA1 mutation linked to breast cancer stem cells
   01-31-2008 · EurekAlert!
   A new study may explain why women with a mutation in the BRCA1 gene face up to an 85 percent lifetime risk of breast cancer. Researchers from the University of Michigan Comprehensive Cancer Center found that BRCA1 plays a role in regulating breast stem cells, the small number of cells that might develop into cancers.

   An international multicenter research effort has identified a new genetic defect as a potential heritable breast cancer susceptibility candidate. The same PALB2 mutation also seems to in some measure cause prostate cancer.

4. Research linking Ashkenazi Jews & breast cancer genes beset by problems
   11-01-2006 · EurekAlert!
   Genetic research over the past decade has linked Ashkenazi Jewish ethnicity to an increased risk for hereditary breast cancer, so much so that certain gene mutations have become known as "Jewish ancestral mutations." But a new study released in the November 2006 issue of the American Journal of Public Health challenges this population-based approach, warning that disparities in access to care and other unintended consequences for specific ethic groups can result, and may have already occurred.

6. Family structure size could affect breast cancer risk prediction accuracy for BRCA gene testing
   06-19-2007 · EurekAlert!
   Researchers have found that the probability of the breast cancer gene mutation BRCA among women with a history of breast cancer is greater when the number of older, female relatives in the family is smaller, according to a study in the June 20 issue of JAMA. This finding may challenge the accuracy of some breast cancer prediction models, which may not take family structure into account.
