摘要
目的探讨维生素D受体(VDR)基因FokI位点F/f单核苷酸多态性(SNP)与Ⅲ型前列腺炎的关系。方法应用聚合酶链反应-限制性片段长度多态性(PCR—RFLP)对103例Ⅲ型前列腺炎患者(A组)及100例非前列腺疾病患者(B组)进行FokI位点SNP检测,分析两组间基因型和等位基因的频率分布。采用Logistic多元回归法分析FokI位点SNP与Ⅲ型前列腺炎的相关性。结果VDR基因FokI位点基因型分布在A组及B组中均符合Hardy.Weinberg平衡。A组基因型分布FF:28%(29/103),Ff:31%(32/103),ff:41%(42/103);B组FF:31%(31/100),Ff:35%(35/100),ff:34%(34/100),其中ff基因型分布在两组中的差异有统计学意义(P〈0.05)。A组等位基因频率分布F:44%(90/206),f:56%(116/206);B组为F:49%(97/200),f:51%(103/200),分布频率差异有统计学意义(P〈0.05)。Logistic回归分析结果显示,FokI多态性是Ⅲ型前列腺炎发生的独立风险因素(P〈0.05)。结论VDR基因FokI位点SNP与Ⅲ型前列腺炎的发生有一定关系。
Objective To investigate the association between F/f single nucleotide polymorphism (SNP) of Fok I in vitamin D receptor (VDR) gene and type Ⅲ prostatitis. Methods In 103 patients with type Ⅲ prostatitis (group A) and 100 control patients without prostatitis (group B), VDR gene FokI SNP was detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The distribution of genotype and allelic frequencies were analyzed. Multiple Logistic analysis was used to examine the association between SNP of Fok I and type Ⅲ prostatitis. Results The genotype distribution of VDR gene FokI was in Hardy-Weinberg equilibrium in both two groups. Genotype distribution of FF, Ff and ff in group A was 28% (29/103), 31% (32/103) and 41% (42/103) respectively, and 31% (31/100), 35% (35/100), 34% (34/100) respectively in group B. There was significant difference between two groups in frequency distribution of ff genotype (P 〈 0. 05 ). The distribution of allelic frequencies of F and f was44% (90/206) and 56% (116/206) in group A, and 49% (97/200), 51% (103/200) in group B, respectively. There was significant difference between two groups in frequency distribution of allele (P 〈 0. 05). The FokI polymorphism was an independent risk factor with type Ⅲ prostatitis by multiple Logistic analysis (P 〈 0. 05 ). Conclusion VDR Foklpolymorphisms are correlated with type Ⅲ prostatitis.
