摘要:

目的 探讨Fcγ受体ⅡA基因多态性和慢性牙周炎的易感性相关关系。方法 采用序列特异性引物多聚酶链反应(PCR-SSP),对63例重度慢性牙周炎患者、103例轻中度慢性牙周炎患者及80名健康对照者的Fcγ受体 ⅡA基因多态性进行检测,比较各组间基因型分布及等位基因频率的差异。结果 FcγRⅡA-R/R131基因型在重度慢性牙周炎与健康对照组之间的分布差异有显著性(P<0·012 5),而在轻中度慢性牙周炎组与健康对照组、重度慢性牙周炎组与轻中度慢性牙周炎组之间的分布差异无显著性(P>0·012 5)。结论 FcγRⅡA-R/R131基因型与慢性牙周炎的严重程度相关,提示其可能与汉族人群慢性牙周炎的易感性有关。

Abstract:

Objective To investigate the association between FcγreceptorⅡAgene polymorphism and susceptibility to chron- ic periodontitis in ChineseHan nationality.Methods DNAsampleswere collectedwith buccal swabs from63 patientswith severe chronic periodontitis(CP), 103 patients with mild to moderate CP and 80 healthy individuals as control. Polymorphism in Fcγre- ceptorⅡA gene cluster was analyzed with PCR-SSP. The genotype distribution and allele frequency among different groups were compared.Results It was found that the frequency of FcγRIIA-R/R131 genotype was significantly higher in patients with severe CP (19·05%) compared to that of the healthy controls (P<0·012 5).Conclusion The FcγRIIA-R/R131 genotype may be one of the contributors for the increased susceptibility to severe CP in Chinese Han nationality.
