New study warns against linking ethnic identity to breast cancer genes

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 issue of The American Journal of Public Health challenges this approach, warning that disparities in access to care and other unintended consequences can, and have, resulted.

   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.

   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.

4. New study reveals for first time how BRCA1 mutations cause breast cancer
   12-09-2007 · EurekAlert!
   An international team of researchers led by Columbia University Medical Center's Herbert Irving Comprehensive Cancer Center and Sweden's Lund University has, for the first time, revealed how mutations in the BRCA1 gene lead to breast cancer. Findings show that one way BRCA1 mutations cause cancer is by knocking out a powerful tumor suppressor gene known as PTEN.

   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.

7. Genesearch Breast Lymph Node assay detects breast cancer metastases with greater sensitivity
   12-16-2006 · EurekAlert!
   Results from a prospective clinical study show that the GeneSearch™ Breast Lymph Node (BLN) Assay, a gene-based diagnostic test has greater sensitivity than traditional intra-operative methods of detecting the spread of breast cancer to the lymph nodes. In the study sponsored by Veridex, LLC, the GeneSearch™ BLN Assay demonstrated overall sensitivity at least 10 percentage points higher than traditional intra-operative tests. The data were presented today at the 29th annual San Antonio Breast Cancer Symposium.

   A new technique called "microarrays" was used in this study, which enables the identification of the specific effects produced by drugs on each human gene. The study, conducted in the Department of Human Anatomy and Embryology at the University of Granada, looked at six new compounds which reduce the side effects of cancer treatment. Results available in Tetrahedron.
