Latest BRCA2 Stories
Preimplantation genetic diagnosis (PGD) for the breast cancer genes BRCA1/2 is now feasible and established, with good success rates for those treated.
Among women with invasive epithelial ovarian cancer, patients having a germline (gene change in a reproductive cell that could be passed to offspring) mutation in the BRCA1 or BRCA2 genes was associated with improved 5-year overall survival, with BRCA2 carriers having the best prognosis.
Women who inherit the cancer genes BRCA1 or BRCA2 from their paternal lineage may get a diagnosis a decade earlier than those women who carry the cancer genes from their mother and her ancestors.
Breast cancer survivors who carry the BRCA1 or BRCA2 genetic mutation are at high risk for developing contralateral breast cancer — a new primary tumor in the other breast — and certain women within this group of carriers are at an even greater risk based on age at diagnosis and first tumor status.
About 10% of breast cancers are due to mutations in genes called BRCA1 and BRCA2.
The largest study of its kind shows that women related to a patient with breast cancer caused by a hereditary mutation, but who don’t have the mutation themselves, have no higher risk of developing cancer than relatives of patients with other types of breast cancer.
Women with high-grade ovarian cancer live longer and respond better to platinum-based chemotherapy when their tumors have BRCA2 genetic mutations.
Among women with a certain type of high-grade ovarian cancer, having BRCA2 genetic mutations, but not BRCA1, was associated with improved overall survival and improved response to chemotherapy, compared to women with BRCA wild-type (genetic type used as a reference to compare genetic mutations).
Women with ovarian cancer who have the BRCA2 gene mutation are more likely to survive the malignancy than women with the BRCA1 mutation, or women without either mutation.
Between 5 % and 10 % of breast cancer cases are hereditary, arising because the patient inherits from the father or mother a mutation in a gene that is susceptible to causing the illness.
