BRCA Gene Changes: Cancer Risk and Genetic Testing
A fact sheet about the BRCA1 and BRCA2 genes, what to do if a person tests positive for alterations in one of these genes, and consequences of genetic testing.
BRCA1 and BRCA2 (PDQ®) - NCI - National Cancer Institute
Evidence-based, expert-reviewed summary about the BRCA1 and BRCA2 genes and hereditary breast and ovarian cancer. This summary also contains information about the cancer risks associated with BRCA1/BRCA2, screening, risk-reduction, treatment, and prognosis.
Hoja informativa sobre los cambios en el gen BRCA y las pruebas …
El BRCA1 (cáncer de mama 1) y el BRCA2 (cáncer de mama 2) son genes que producen proteínas que reparan daños en el ácido desoxirribonucleico (ADN). Cada persona hereda dos copias de cada uno de estos genes: una de la madre y otra del padre.
MRI, Surgery Reduce Cancer Deaths in Women with BRCA Changes
Apr 15, 2024 · Those with harmful BRCA1 or BRCA2 changes who had the surgery, the study found, had a lower risk of dying from ovarian cancer and breast cancer than those who didn’t.
Discovery – BRCA Connection to Breast and Ovarian Cancer
NCI-funded research helped identify inherited BRCA1 and BRCA2 genetic mutations and their connection to breast and ovarian cancer. From this research, a screening test was also developed to help patients make informed decisions about their health.
Definición de gen BRCA1 - Diccionario de cáncer del NCI
Gen que da origen a una proteína que repara el ADN dañado. Las mutaciones (cambios) en el gen BRCA1 aumentan mucho el riesgo de presentar cáncer de mama y cáncer de ovario. También aumentan el riesgo de presentar otros tipos de cáncer, como el …
Olaparib Approved for Breast Cancers with BRCA Gene Mutations
Jan 29, 2018 · The Food and Drug Administration has approved olaparib (Lynparza®) to treat metastatic breast cancers that have inherited mutations in the BRCA1 or BRCA2 genes as well as a companion diagnostic test for selecting candidates for the therapy.
Olaparib for Pancreatic Cancer with BRCA Mutations - NCI
Jun 26, 2019 · Olaparib (Lynparza) may benefit some people with advanced pancreatic cancer who have BRCA1 or BRCA2 mutations, according to the POLO trial results.
Individual Champion/Changemaker | Division of Cancer Prevention
Long before scientists completed mapping the human genome in 2003, geneticist Mary-Claire King discovered BRCA1, the first gene for a hereditary form of breast cancer. That feat in 1990 helped explain why some women who carried mutations in this gene saw their lifetime risk for developing breast cancer rise from 8% to over 80%.
PALB2 and Associated Cancer Risks (PDQ®) - NCI
Feb 14, 2025 · The PALB2 (Partner And Localizer of BRCA2) gene is located on chromosome 16p12.2. This gene interacts with both BRCA2 and BRCA1 to restore and maintain genomic stability via homologous recombination repair of DNA double-stranded breaks. Several studies have reported a high penetrance of breast cancer in …
