摘要: 目的: 建立ABCG2 34G>A和421C>A单核苷酸多态性位点的焦磷酸测序方法。 方法: 抽取志愿者静脉血入EDTA抗凝管,常规苯酚/氯仿法制备全血gDNA,生物素标记引物对扩增多态位点目的片段,制备生物素标记单链模板,与测序引物退火结合后行焦磷酸测序。分析结果经毛细管电泳测序验证,并进行重复性检验。 结果: 本文建立了针对ABCG2 34G>A和421C>A多态性位点的焦磷酸测序方法,经毛细管电泳测序验证和重复性验证,结果准确可靠。ABCG2 34G和34A等位基因频率分别为 79.5%和 20.5%;421C和421A等位基因频率分别为 72.7%和 27.8%,均符合Hardy-Weinberg平衡。 结论: 本文建立的焦磷酸测序方法可准确、高通量、快速检测ABCG2 34G>A和421C>A单核苷酸多态性,并且特别适宜大样本量的临床及科研批量检测需要。

Abstract: AIM: To establish a pyrosequencing based method for detection ABCG2 34G>A and 421C>A polymorphisms and to determine the frequency of these polymorphisms in healthy Chinese. METHODS: After preparation of gDNA from blood of 200 subjects, the target fragments were amplified by PCR, polymorphisms were detected on PyroMark ID by pyrosequencing technology. The reliability of pyrosequencing methods were validated by repeat tests and Sanger sequencing. RESULTS: We established a new pyrosequencing method to detect the ABCG2 34G>A and 421C>A polymorphisms polymorphisms in healthy Chinese. The detection rate and repetition rate were both 100%. The frequencies of ABCG2 34G and 34A alleles were 79.5% and 20.5%, respectively. The allele frequencies of ABCG2 421C and 421A were 72.7% and 27.8%, respectively. Genotype frequencies match the Hardy-Weinberg equilibrium. CONCLUSION: These pyrosequencing assays to detect ABCG2 polymorphisms are proved to be a rapid, accurate and high-throughput alternative to conventional methods, and it can be a preferred option in research and clinical application.
