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)与乳腺癌家族史的乳腺癌...

SEATTLE – Women with breast cancer before age 55 who carry an inherited mutation in the breast cancer susceptibility genes BRCA1 or BRCA2 are four times more likely to develop cancer in the breast opposite, or contralateral, to their initial tumorcancernews.com...
BRCA 基因全称为乳腺癌易感基因(breast cancer susceptibility gene,BRCA),主要有两种类型:BRCA1、BRCA2,分别在 1990 年和 1994 年研究遗传性乳腺癌相关病因时被发现。 BRCA1/2 基因均在 DNA 损伤修复、细胞的正常生长方面发挥重要作用,具有抑制肿瘤和促进 DNA 损伤修复的作用。一旦发生突变,其 DNA 损伤修复功能受...
Breast Cancer Susceptibility Gene 1/2( BRCA1/2)即乳腺癌易感基因 1和乳腺癌易感基因2。它们是人体中两个重要的抑癌基因,是我们身体里的 “抗癌卫士”。它们负责维持细胞的遗传稳定性,帮助修复受损的 DNA,防止细胞发生癌变。然而,当 BRCA1/2 基因...
刚才只提到了BRCA1,其实还有个BRCA2,这两个成员同属于BRCA基因家族,他们的全称叫做Breast Cancer Susceptibility gene。本该是优秀的抑癌基因,像我们身体中的“医生”,但如果出现某个基因点位的变异,甚至是成段、成片的错配,那么免疫功能就会存在异常,无法正常发挥修复功能。当确认这种突变为“致病突变”时,被称为“...
BRCA2 (breast cancer 2, early onset) is a protein-coding gene. Diseases associated with BRCA2 include fanconi anemia, complementation group d1, and breast-ovarian cancer, familial, 2. GO annotations related to this gene include histone acetyltransferase
Little is known about how the breast cancer (BRCA) gene mutation affects women’s decision-making processes. I use a feminist standpoint lens to explore the process by which BRCA-positive women came to socially construct and understand their risk for developing breast and/or ovarian cancer and ...

[Abstract]Germline mutations in BRCA genes (including BRCA1/2) are the major risk factors for hereditary tumors including breast and ovarian cancer. Population based BRCA gene screening, particularly in high-risk individuals with a family history of cancer, can play a preventive role by reducing ...
