摘要
目的探讨CYP27B1(Cytochromo P450 CYP)基因启动子C-1260A位点多态性与宁夏汉族Graves病(GD)的相关性。方法采用聚合酶链反应-限制性片段长度多态性(polymerase chain reaction restriction frag-ment length polymorphism,PCR-RFLP)技术,分析汉族GD 99例和正常对照83例CYP27B1基因启动子-1260C/A多态性。结果宁夏汉族CYP27B1基因-1260C/A检出GD组与对照组的基因型频率分别为37.37%、53.54%、9.09%和43.37%、40.96%、15.66%,两组差异无统计学意义(χ2=4.19,P>0.05);等位基因频率为64.16%、35.86%和63.86%、43.14%,两组差异无统计学意义(χ2=0.00,P>0.05)。结论 CYP27B1基因1260C/A的与宁夏地区汉族GD无相关性。
Objective To investigate the association between CYP27B1 gene promoter polymorphisms and patients with Graves' disease in Ningxia Han People.Methods A case control study was performed for CYP27B1(1260 C/A) in the promoter region in 99 patients with GD and 83 healthy individuals.The CYP27B1 genotype all cases and control were examined of by polymerase chain reaction restriction fragment length polymorphism(PCR-RFLP).Results In the promoter(1260) of CYP27B1 gene,the frequencies of genotypes and C/A allele showed no significant difference between cases and controls(P0.05).Conclusion The position 1260 C/A in the promoter of CYP27B1 may be not susceptible to GD in Ningxia Han people.
