Abstract: Objective To establish a method for SNP polymorphism analysis based on pyrosequencing and pooling technology. Methods A sample pooling of 50 unrelated individuals was set up for pyrosequencing testing. PyroMark Assay Design 2.0 software was adopted to design primer for allelic quantification. Afterwards, PCR products of the pooling samples were pyrosequenced. Results The polymorphism of three target SNP loci was observed. Moreover, for rs220028, there is no significant difference between the testing results and previous data based on population survey. Conclusion The established SNP analysis method based on pyrosequencing and pooling technology is accurate, reliable and easy to perform. It is suitable for the screening and investigation of large population.
