Genomic DNA was extracted from peripheral blood of 194 COPD smokers and 201 healthy smokers of Uighur who were hospitalized in or paid a visit to one of the four Xingjiang-based hospi-tals involved in the study, betweenfrom March 2009 to December 2010. Single nucleotide polymor-phisms (SNPs) were studied on A/G atwithin amino acid aa62 (CCA/CCG rs1136451) and C/T within aa219 (CGG/TGG, rs4253527) in SP-A. Genotypes were determined by using the TaqMan polymerase chain reaction (PCR). Our results showed that genotype frequencies were different be-tween the COPD and normal smokers infor aa62 (χx2=6.852, P=0.033). There were also significant differences in allele genotype frequencies between the COPD and the control and allele G might de-crease the risk COPD (χx2=6.545, P=0.011; OR=0.663; 95% CI: 0.484–0.909). The result suggested We were led to conclude that polymorphism of aa62 (CCA/CCG, rs1136451) of SP-A may be asso-ciated with the susceptibility to COPD in Xingjiang Uighurs.展开更多
