The risk of developing cancer is not identical for all carriers of BRCA1 and BRCA2 mutations. Risk can be influenced by allelic heterogeneity, modifier genes, and environmental and hormonal cofactors. Abstract The discovery of the first gene associated with hereditary breast cancer, BRCA1, was ant...
通过分析14种癌症患者携带BRCA1/BRCA2致病性突变的频率,研究团队发现,男性乳腺癌患者携带BRCA2致病性突变的频率较高(18.9%);卵巢癌患者携带致病性突变的频率次之,其中4.86%存在BRCA1致病性突变,3.42%存在BRCA2致病性突变。 此外,还有6种癌症类型患者携带致病性突变的频率超过1%,其中2种携带BRCA1致病性突变,4种携带BRCA2...

The proteins encoded by the two major breast cancer susceptibility genes,BRCA1andBRCA2, work in a common pathway of genome protection. However, the two proteins work at different stages in the DNA damage response (DDR) and in DNA repair. BRCA1 is a pleiotropic DDR protein that functions in...
本研究结果扩大了与BRCA1和BRCA2致病性突变相关的癌症类型范围,明确了有相关癌症家族史的个体进行基因检测的临床意义,同时为这些癌症患者的治疗提供了更多选择。 在20世纪90年代,研究人员证明了BRCA1和BRCA2为遗传性乳腺癌和卵巢癌的致病基因[1]。 时至今日,我们都知道携带BRCA1和BRCA2基因突变的人群患乳腺癌和卵巢...
时至今日,我们都知道携带BRCA1和BRCA2基因突变的人群患乳腺癌和卵巢癌的风险增加,且BRCA1和BRCA2突变携带者患乳腺癌的风险与被诊断为乳腺癌的近亲数量呈正相关[2]。 随着对这两个基因研究的深入,人们发现在前列腺癌和胰腺癌中,BRCA1和BRCA2致病性突变频率也增加,因此与这两个基因有关的癌症类型进一步扩展[3-4]...
Genes can develop abnormalities that change how the cell works. Breast Cancer Genes Abnormalities (mutations) in two genes -- BRCA1 and BRCA2 - are the most common causes of hereditary breastcancer, accounting for about 20% to 25% of cases. ...
BRCA1 and BRCA2: different roles in a common pathway of genome protection. The proteins encoded by the two major breast cancer susceptibility genes, BRCA1 and BRCA2, work in a common pathway of genome protection. However, the two ... R Roy,J Chun,SN Powell - 《Nature Reviews Cancer》 ...
The BRCA1 protein, a hereditary breast and ovarian cancer-causing gene product, is known as a multifunctional protein that performs various functions in cells. It is well known, along with BRCA 2, to cause hereditary breast and ovarian cancer, but here we will specifically focus on BRCA1. We...
