摘要 目的探讨中国汉族人群Sirtuin 2基因Intron8(rs7257949A/T)多态性与散发帕金森病(PD)的关系。方法采用病例-对照研究、聚合酶链反应--限制性片段长度多态性(PCR-RFLP)方法分析了82例PD患者(PD组)与103例健康成人(对照组)Sirtuin 2基因rs7257949A/T位点多态性。结果病例组SIRT2基因rs7257949A/T多态性的AA基因型20.7%(17/82),T等位基因携带者为79.3%(65/82);而对照组分别为AA型7.8%(8/103),T等位基因携带者为92.2% (95/103)。经χ2检验两组之间的差异有统计学意义(χ2=6.566,P=0.010)。病例组A、T等位基因频率分别为48.6%(70/144),51.4%(74/144);对照组A、T等位基因频率分别为34.0%(70/206),66.0%(136/206)。经χ2检验两组之间的差异有统计学意义(χ2=7.559,P=0.006)。结论中国汉族人群Sirtuin 2基因Intron8(rs7257949A/T)多态性的纯合子AA可能是PD的遗传易感性基因型。 Objective To explore the relationship between the intron 8 (rs7257949A/T) polymorphism of sirtuin 2 (SIRT2) gene and sporadic Parkinson's disease (PD). Methods The PCR--RFLP (Restriction fragment length polymorphism) method was used to determine rs7257949A/T polymorphism in Intron 8 of SIRT2 gene in the case group ( n = 82) and healthy control group ( n = 103). Results The AA and T allele carriers genotyping frequencies of rs7257949 in the case group were 20.7%(17/82) and 79.3% (65/82) and that in healthy control group were 7.8% (8/103) and 92.2% (95/103), respectively. Chi--square analyses showed that the difference of these genotyping frequencies between the case group and healthy control group was significant (P〈0. 05). The frequency of allele(A and T)was 48. 6% (70/144), 51.4% (74/144) in the case group and 34.0% (70/206), 66.0% (136/ 206)in healthy control group, respectively. Chi--square analyses showed that the difference of the frequency of allele(A and T) between the case group and healthy control was significant (P 〈 0.05). Conclusions The results indicated that the polymorphism of Intron 8 (rs7257949A/T) in sirtuin 2 gene maybe the predisposing gene of PD in Chinese Han population.
