Objective To investigate the frequencies of variant of lipoprotein lipase(LPL)gene,HindIII site at intron 8 and PvuII site at intron 6,and its relation with type 2 diabetes mellitus and insulin resistance(IR).Methods PCR-RFLP method was used to determine the DNA polymorphism of 8 th intron and 6 th intron of LPL gene in 78 T2DM patients and 49 controls.Results(1)Compared with control group,the frequencies of H+H+ genotypes and alleles ″H+″ was significantly higher in type 2 diabetes patients(P
