Objective: To study the relationship between the lipoprotein lipase(LPL) gene and type 2 diabetes mellitus (DM) and its lipid metabolism.
Methods: PCR-RFLP method was used to determine the DNA polymorphism of 6th intron at LPL gene in 127 DM patients and 125 controls.
Results: The allele frequencies in case and control groups were 69.3%, 63.6% for "P+" and 30.7%, 36.4% for "P-", respectively; the frequencies of genotypes were 48.0%, 44.8% for P+/P+, 42.5%, 37. 6% for P+/P- and 9.45%, 17.6% for P-/P-, respectively. There was no significant difference in frequencies of genotypes or alleles between the two groups. The LPL Pvu II polymorphism in Chinese population was similar to that in Japanese population, and was different from that in European and American population.
Conclusion: The LPL-Pvu II-RFLP in Chinese population is not significantly associated with type 2 diabetes mellitus. The significant difference of Pvu II-RFLP among various races was observed.
