Description
技术领域
本发明属于分子生物学领域,涉及医学和生物技术,具体涉及一种女性乳腺癌发病风险的基因检测试剂盒,根据检测结果从基因层面评估女性乳腺癌发病的风险,并作为预防女性乳腺癌的建议指导。
背景技术
乳腺癌是女性最常见的恶性肿瘤之一,发病率占全身各种恶性肿瘤的7-10%,位居女性恶性肿瘤发病率的第一位。近年随着环境和人口老龄化的影响,乳腺癌的发病率有明显增高的趋势。早期发现并及时治疗是乳腺癌防治的关键。
人类基因组计划的完成使我们对癌症发生的分子机制认识进入了新的阶段。基因多态性(singlenucleotidepolymorphism,SNP)普遍存在于机体DNA序列中,是第三代遗传标记。SNP研究是人类基因组计划走向应用的重要步骤。因为SNP可作为一个强有力的工具,用于高危群体的发现、疾病相关基因的鉴定、药物的设计和测试以及生物学的基础研究等。通过病例对照研究不仅对于发现癌症相关基因及阐明其作用机制起着重要作用,而且对于癌症易感性早期风险诊断和个体化医疗具有重要意义。
与乳腺癌的发病直接或间接相关的基因众多,其多态性位点变异可影响乳腺癌的发病风险,因此建立简单、可靠、快速的乳腺癌遗传易感性的无创检测方法,能够检测出乳腺癌发生相关的基因单核苷酸位点基因型,及时筛查出乳腺癌易感高危人群,从而根据检测结果尽早采取预防措施,这对于提高乳腺癌的早诊早治有重要意义。

具体实施方式
。ESR1基因编码雌激素受体。COMT编码儿茶酚-O-甲基转移酶,与雌激素的灭活相关。COMT第4号外显子上一个G>A多态性位点突变,导致其第158位密码子编码的氨基酸有Val变为Met。COMT基因的Val和Met等位基因与儿茶酚-O-甲基转移酶活性高低相关,Val/Val基因型酶具有高活性,Val/Met基因型酶活性中等,Met/Met基因型酶活性最低。研究表明该多态性位点与乳腺癌发病相关。CYP19A1基因编码细胞色素P450芳香化酶是雌激素合成酶,rs10046位于CYP19A1基因的3’UTR区,rs700519多态性位点导致R264C变异。SHBG编码雌激素结合球蛋白,GSTP1编码Ⅱ相代谢酶谷胱甘肽转硫酶。
