Pyrosequencing of clinically relevant polymorphisms.

Despite the influx of high throughput sequencing techniques, there is still a niche for low-medium throughput genotyping technologies for small-scale screening and validation purposes. 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 utilized to identify tri-allelic, indel, and short repeat polymorphisms, as well as determining allele percentages for methylation or pooled sample assessment. This range of applications makes it well-suited to the research laboratory as a one-stop system.
