The function of their large, nuclear-localised protein products remains uncertain, but they have been implicated in the cellular response to DNA damage and in the regulation of gene transcription. BRCA1 and BRCA2 are highly distinct genes, despite the similarity in their acronyms. Characteristics ...
Inherited inactivating mutations inBRCA1 or BRCA2seem to cause a similar predisposition to breast and ovarian cancer, but a closer look reveals many differences as well. This Perspective discusses the similarities and differences between BRCA1 and BRCA2
1、 brca1和brca2基因在前列腺癌中的研究进展 郑立传 康郑军 张英豪 徐文博【摘要】 家族史是前列腺癌的危险因素之一,乳腺癌易感基因2(brca2)为已证实的前列腺癌高危遗传因素。虽然brca2和brca1在前列腺癌发病中的作用机制尚未明确,但两者均为有害突变基因,与肿瘤的侵袭性和疾病的不良临床预后相关。前列腺癌的...
基于当前对乳腺癌易感基因(breast cancer gene 1,BRCA1)和乳腺癌易感基因2(breast cancer gene 2,BRCA2)在乳腺癌中发病、预防、治疗及预后认识的深化、检测技术的成熟以及新靶向药物的应用,中国医师协会精准治疗委员会乳腺癌专专业委员...
BRCA gene, Breast cancer, Hakka population, Ovarian cancer, Variants. 基因检测临床研究与应用结果介绍: 目的:调查中国客家人乳腺癌和卵巢癌患者BRCA1和BRCA2突变的流行情况和谱。方法:共招募1664例乳腺癌或卵巢癌患者在我院进行基因检测。通过二代测序基因检测分析BRCA基因的种系突变,包括编码区和外显子内含子边...
In 2008, an estimated 21,650 women were diag- nosed with ovarian cancer.1 Approximately 8% to 15% of these ovarian cancers are attributable to a hereditary predisposition to breast and ovarian cancer caused by germ line mutation of the BRCA1 or BRCA2 gene.2–4 In addition, a small ...
