Thirty years after the sequencing of the BRCA1 cancer-associated gene, access to genetic tests and awareness about its risks ...

新研究表明在HER2阳性乳腺癌患者中，胚系BRCA1/2突变的发生率为6.6%，且不影响生存结果。乳腺癌是女性最常见的恶性肿瘤，遗传易感性作为其主要风险因素，在全部乳腺癌病例中占比达5%-10%。其中，约50%的病例与乳腺癌相关基因BRCA1和BRC ...

研究人员发现，即使没有二次突变，单个错误的BRCA1拷贝也会使乳腺细胞更容易罹患癌症，并足以引发肿瘤生长。这项研究成果于2024年11月11日发表在《Nature Genetics》杂志上。 众所周知，我们从父母那里获得了每个基因的两个拷贝，这是进化过程中的一个防故障 ...

据《美国医学会杂志》发表的研究披露，研究人员开展的一项分析包括了近1万名BRCA1 或 BRCA2基因变异的妇女，这项分析旨在估测有这些基因突变的 ...

Adjuvant Lynparza remains beneficial for patients with BRCA1/2 mutation–positive, HER2-negative high-risk breast cancer, study results have shown.
