Study on relationship between polymorphism of TNF-?and IgA nephropathy of Han nationality Chinese in inner Mongolia Autonomous Region / 临床检验杂志

Objective To study the relationship of tumor necrosis factor beta (TNF-?) polymorphism with human IgA nephropathy of Chinese Han nationality in Inner Mongolia Autonomous Region. Methods The A→G single base mutation polymorphism in TNF-?1096 locus were analyzed among 80 normal controls and 79 IgA nephropathy patients by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results The genotype frequencies of TNF?* 1/1 and TNF?* 2/2 in IgA nephropathy patients were significantly higher than that in normal controls (x1/12=5.58,P
