乳腺癌易感基因(breast cancer susceptibility gene, BRCA)与乳腺癌有着密不可分的关系。 BRCA基因 的两个成员,即BRCA1和2,分别是在1990年和1994年被分离。 乳腺癌可以分为 遗传性乳腺癌 和 散发性乳腺癌 (sporadic breast cancer),散发性乳腺癌指的是没有发现明确的遗传基因改变(完整的癌变点)与乳腺癌家族史...
BRCA基因是什么? BRCA基因,即乳腺癌易感基因(Breast cancer susceptibility gene),包括BRCA1和BRCA2两种类型,是主要的抑癌基因,参与同源重组修复过程,在细胞周期调控和基因组完整性维持中起关键作用。 BRCA基因突变会带来哪些后果? 当该基因发生突变时,其修复功能可能会受到影响,约5%-10%的乳腺癌和15%-22%的卵巢癌...
FDA原文如下: The U.S. Food and Drug Administration today authorized the Personal Genome Service Genetic Health Risk (GHR) Report for BRCA1/BRCA2 (Selected Variants). It is the first direct-to-consumer (DTC) test to report on three specific BRCA1/BRCA2 breast cancer gene mutations that are...
一、什么是BRCA基因? BRCA基因,即乳腺癌易感基因(Breast cancer susceptibility gene),包括BRCA1和BRCA2两种类型,分别位于我们的第17号和第13号染色体上。它们可以被比喻为我们体内的“哨兵”,防止健康细胞走向癌变的道路。通常,这些基因“哨兵”能够忠诚地执行它们的职责。然而,当BRCA基因发生突变时,它们的功能就会受...

BRCA1 (breast and ovarian cancer susceptibility protein 1) is a nuclear phosphoprotein that plays a role in maintaining genomic stability and acts as a tumor suppressor in combination with other tumor suppressors, DNA damage sensors, and signal transducers to form a large multi-subunit protein compl...
