基因突变也是生物进化的重要因素之一。基因突变(Genemutation)是由于Dna分子中发生碱基对的增添、缺失或替换,而引起的基因结构的改变,就叫做基因突变。基因突变在自然界各物种中普遍存在。 正在加载... 百度健康内容支持 如有医疗需求,请务必前往正规医院就诊 产品建议及投诉请联系:ext_bdjk-kf@baidu.com...

The encoded protein combines with other tumor suppressors, DNA damage sensors, and signal transducers to form a large multi-subunit protein complex known as the BRCA1-associated genome surveillance complex (BASC). This gene product associates with RNA polymerase II, and through the C-terminal ...

乳腺癌易感基因(breast cancer susceptibility gene,BRCA)包括BRCA1和BRCA2,是目前最被熟知的抑癌基因之一,其编码产物参与DNA损伤同源性重组修复,维持细胞的正常功能[1]。BRCA1/2基因突变会导致同源重组缺陷,使得基因组不稳定性显著增加,与包括乳腺癌、卵巢癌、前列...
BRCA1/BRCA2 基因检测 新基因格医学 重大疾病检验 BRCA(BReast CAncer susceptibility gene;乳腺癌易感基因)是重要的抑癌基因与肿瘤易感基因,包括BRCA1及BRCA2。BRCA基因突变会导致基因组不稳定性显著增加,从而显著提高女性罹患乳腺癌、卵巢癌以及其他癌症(如:胰腺癌、子宫内膜癌、腹膜癌及宫颈癌等[1-4])的风险。

乳腺癌是女性中最常见的肿瘤,在有乳腺癌家族史的的女性中大约有20%左右的患者会出现BRCA1或BRCA2基因的突变[1]。BRCA1失去功能的突变与易患早发型乳腺癌和卵巢癌有关。 BRCA1基因较大,包含24个外显子,其功能主要与基因组的稳定性、DNA双链断裂同源重组修复密切相关。虽然已发现的BRCA1基因变异有数千种,但许多...
BRCA1/2基因突变分为两种类型:一种为胚系突变(germline mutation,gBRCAmut),是指来源于精子或卵母细胞的生殖细胞突变,导致机体所有细胞都带有突变,可以遗传给后代;另一种为体细胞突变(somatic mutation,sBRCAmut),是指发生于肿瘤细胞中的BRCA基因突变,为非遗传性突变。胚系...
