The data generated from the Human Genome Project has led to an explosion of technology for low-, medium-, and high-throughput genotyping methods. Pyrosequencing is a genotyping assay based on sequencing by synthesis. Short runs of sequence around each polymorphism are generated, allowing for internal controls for each sample. Pyrosequencing can also be used to identify tri-allelic, indel, and short-repeat polymorphisms, as well as determining allele percentages for methylation or pooled sample assessment. Assays details for Pyrosequencing of clinically relevant polymorphisms are described in this chapter.
人类基因组计划产生的数据引发了低、中、高通量基因分型方法技术的爆炸式发展。焦磷酸测序是一种基于合成测序的基因分型检测方法。围绕每个多态性位点生成短序列片段,可为每个样本提供内部对照。焦磷酸测序还可用于识别三等位基因、插入缺失和短重复多态性,以及确定甲基化或混合样本评估的等位基因百分比。本章介绍了临床相关多态性焦磷酸测序的检测细节。
