We have hypothesized a possible relationship between disc degeneration (DD) and VDR FokI/T2C polymorphism.
A case-control study was performed comprising 121 Brazilian patients with confirmed DD by nuclear magnetic resonance and a control group consisting of 131 healthy patients without a history of disc cysts of the lumbar spine. Detection of VDR FokI/T2C polymorphism was performed using restriction fragment length polymorphism-polymerase chain reaction. The chi-square test was used to compare allele and genotype frequencies between groups, and a p-value of <0.05 was considered statistically significant.
The results disclosed statistical difference between allele distribution among cases and controls (p=0.025, odds ratio=1.58, confidence interval=1.07-2.32) considering VDR FokI/T2C polymorphism.
The results showed a positive association between VDR FokI/T2C polymorphism and DD in Brazilian patients tested.
我们推测椎间盘退变(DD)与维生素D受体(VDR)FokI/T2C多态性之间可能存在关联。
进行了一项病例对照研究,包括121例经核磁共振确诊为DD的巴西患者,以及一个由131例无腰椎间盘囊肿病史的健康患者组成的对照组。采用限制性片段长度多态性-聚合酶链反应检测VDR FokI/T2C多态性。使用卡方检验比较两组之间的等位基因和基因型频率,p值<0.05被认为具有统计学意义。
考虑VDR FokI/T2C多态性时,病例组和对照组之间的等位基因分布存在统计学差异(p = 0.025,比值比 = 1.58,置信区间 = 1.07 - 2.32)。
结果显示,在接受检测的巴西患者中,VDR FokI/T2C多态性与DD之间存在正相关。
