Understanding the BRCA 1 Mutation

More than 10 years ago, scientists discovered that mutations in a gene called BRCA1 lead to a particularly deadly type of breast cancer. Now scientists have found another gene that may explain why. The gene PTEN has instructions to produce a protein that stops the uncontrolled cell growth of cancer. But BRCA 1 prevents PTEN from doing its work of suppressing cancer. That could explain why the 15 - 20% of women who have the BRCA 1 mutation are at a higher risk of getting breast cancer. The research, published in the journal Nature Genetics, might help scientists better fight breast cancer.
