This article will examine current knowledge about BRCA1 and BRCA2 genetic testing for ovarian cancer and follow the journey taken by women who are considering such testing. Genetic counselling and genetic testing will be critically evaluated and the implications for clinical practice, the individual ...
In the ten years since the discovery of BRCA1 and BRCA2, genetic testing for breast and ovarian cancer susceptibility has become integrated into the practice of clinical oncology. Attempts to identify a third breast cancer susceptibility locus (BRCA3) have so far been unsuccessful. This is probab...
研究最后指出,BRCA1和BRCA2是两种常被人提及的乳腺癌、卵巢癌易感基因。现有研究显示,大约有5%-10%的乳腺癌是由某种遗传性基因突变引起的;大约有5%-15%的卵巢癌患者,都有至少一种BRCA基因突变。如果男性遗传了BRCA2基因突变,不仅会增加乳腺癌风险,还会增加前列腺癌的风险。 这项研究的发现强调了“携带BRCA1或BRCA...

通过对brca1/2基因的检测,寻找其致病突变位点,筛检出乳腺癌、卵巢癌及其他相关恶性肿瘤的高危人群,利于该类疾病的早期诊断治疗和风险评估。而此前美国国家癌症研究所发布的《brca1andbrca2:cancerriskandgenetictesting》指南也指出:先对家族中罹患乳腺癌或卵巢癌的患者进行基因检测,如果发现该患者带有有害的brca1或...

国内研究数据显示中国乳腺癌中BRCA1/2 致病性胚系突变率为5.3%,其中家族性乳腺癌患者中为18%[3]。BRCA1/2突变携带者70岁累积乳腺癌发病风险分别为37.9% 和36.5% [4]。对侧乳腺癌10年累积风险分别为15.5%和17.5%,是非突变携带者的4～5 倍[5]。病例对照回顾性研究分析,TP53、BRCA1、BRCA2和PALB2是中国女性...
