摘要
Objective:To establish a new detecting method for disease susceptibility loci R1628P and G2385R of Parkinson’s disease(PD)related gene LRRK2.Methods:Sequence specific primers were designed to make a genotyping of DNA markers with known genotypes by use of quantitative fluorescence real-time PCR(RT-PCR).100 cases of PD samples with unknown genotypes were tested,and verified by use of polymerase chain reaction linked restriction fragment length polymorphism(PCR-RLFP).Results:The genotyping results of DNA markers proved to be correct,and 100 cases of samples to be tested had a completely consistent genotyping result with PCR-RLFP genotyping result.Conclusions:Sequence specific primer and quantitative fluorescence RT-PCR can successfully make a genotyping for disease susceptibility loci R1628P and G2385R of LRRK2.
