Objective:To investigate the relationship of Megsin gene C25663G polymorphism and IgA nephropathy in Chinese Han population.Methods:471 IgAN patients, their family members and 197 normal controls were recruited. Genotypes of Megsin gene C25663G were identified by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP). The results was analysed by transmission Disequilibrium Test(TDT),haplotype relative risk(HRR) and case-control analyses.According to their disease stability, IgAN patien...
