PurposePolymorphisms of several candidate genes have been studied and associated with the development of chronic obstructive pulmonary disease (COPD). One such candidate is the SERPINE2 (Serpin peptidase inhibitor, clade E member 2) gene.Materials And MethodsTo assess whether the SERPINE2 gene is associated with COPD in a Chinese Han population. Samples were collected from a Chinese Han population and analyzed for the association of single nucleotide polymor phisms (SNPs) or haplotypes of SERPINE2 gene with COPD in a case-control study. Three SNPs including rs840088 G/A in intron 1, rs1438831 A/G in 5' upstream sequence and rs3795879 G/A in intron 3 were detected using the polymerase chain reaction (PCR)-based restriction fragment length polymorphism technique in 409 COPD subjects and 411 controls. Genotyping of the SREPINE2 polymorphisms at positions rs840088, rs1438831and rs3795879 was performed.ResultsWe found that none of the rs840088G/A, rs1438831G/A and rs3795879 G/A polymorphisms were associated with the disease. The p-values were 0.630, 0.208 and 0.398 respectively.ConclusionOur data suggested that there was no significant association between SERPINE2 polymorphism and COPD susceptibility in the Chinese Han population.
