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...

乳腺癌易感基因(breast cancer susceptibility gene,BRCA)是重要的抑癌基因,包括BRCA1和BRCA2。BRCA1/2基因是评估乳腺癌、卵巢癌和其他相关癌症发病风险的重要生物标志物,也是影响患者个体化治疗方案选择的生物标志物,所以BRCA检测具有重要的临床意义。BRCA基因检测难度较大,没有热点变异,变异遍布于2个基因的全长,变异...
