The article advises women about the association between breast cancer (BC) and the presence of a mutation in BC susceptibility gene 1 or 2 (BRCA1/2). Diagnosis of the presence of a BRCA mutation involves genetic testing of a small blood sample. According to the authors, women who have ...
Either mutation brings an increased risk of developing breast cancer at a younger age (before menopause). People who have a mutated BRCA1 or BRCA2 gene have an increased risk of developing a second primary breast cancer. Bilateral breast cancer (cancer in both breasts) is also more common in...
A cohort study published in JAMA Network Open found that patients with breast cancer and pathogenic BRCA1/2 variants treated with breast-conserving therapy (BCT) had above-average risks of ipsilateral and contralateral breast cancer events, but most did not have another cancer event and rem...

Breast cancer susceptibility genes. BRCA1 and BRCA2. Mutations in the BRCA1 and BRCA2 genes lead to an increased susceptibility to breast, ovarian, and other cancers. It is estimated that 3%-8% of all women w... LC Brody,BB Biesecker - 《Medicine》 被引量: 286发表: 1998年 The freque...
Breast Cancer susceptibility gene 1 (BRCA1) & Breast Cancer Breast cancer is one of the most common malignancies affecting women worldwide. About 5-10% of all cases are estimated to be familial. Mutations in the BRCA1 (Breast Cancer susceptibility gene 1) gene account for about 15-20% of...

Breast cancer susceptibility gene 1(BRCA1) is a tumor suppressor gene, whose encoded proteins play an important role in cell-cycle regulation, DNA damage repair, induction of apoptosis in damaged cells and the maintenance of genomic stab... CX Mao,FR Lin - 《Journal of Leukemia & Lymphoma》...
Jolie has a genetic mutation to one of her BRCA genes—specifically the BRCA1 gene. We all have BRCA genes, which function as tumor suppressors. These genes are essential for healthy cell survival andcancer prevention. They act to repair our DNA and fix errors that occur due to aging or ...
Epigenetic scars ofBrca1loss point toward breast cancer cell of origin The two-hit hypothesis suggests that a second mutation is necessary for cancer development in cells with a defective tumor-suppressor gene, such asBRCA1. However, a study now shows that the loss of just oneBrca1allele in ...
