Polymerase Chain Reaction-Sequence Special Primers in Detecting Gene Polymorphism of Pediatrics Diseases / 实用儿科临床杂志

ABSTRACT

Objective To establish an approach of polymerase chain reaction-sequence special primers(PCR-SSP) to perform polymorphism analysis for multiple genes simultaneously,in order to be used in clinical analysis.Methods The optimized PCR-SSP approach was used to analyze the polymorphism of the following genes:mutation of-308A/G and-238G/A in tumor necrosis factor-?((TNF-?)),-174G/C in interleukin-6(IL-6).Results Polymorphism analysis of multiple genes and many clinical samples could be simultaneously performed with one PCR program,showing clear genotype,quick and accurate genotype.Conclusion The optimized(PCR-SSP) is suitable for polymorphism analysis of the large-sample polygenic mononcleeotide point mutation,and it can be widely applied in clinical test for low cost,quickness and accuracy.
