摘要
目的通过病例对照研究明确结核感染与NRAMP1基因多态性的关系。方法选择127例活动性肺结核患者,均为汉族,平均年龄52.5岁,另选与民族匹配的58例健康对照者。对上述入选者通过聚合酶链反应限制性片段长度多态性(PCRRFLP)分析对NRAMP1基因多态性——内含子4(INT4)、D543N进行检测。结果两种NRAMP1基因多态性均与痰涂片阳性的结核显著相关。在结核患者中INT4与D543N的杂合子形式为对结核易感的多态性。NRAMP1的不同基因多态性的协同作用导致了对结核的易感性。结论NRAMP1基因多态性可以影响中国汉族人群对结核的易感性。
Objective To elucidate the relationship between polymorphisms of NRAMP1 gene and susceptibility to tuberculosis in Chinese Han nation by case control study. Methods We selected 127 patients with active pulmonary tuberculosis who were all Han people with mean age of 52.5 years and 58 ethnically matched healthy controls. We typed the polymorphisms of NRAMP1, INT4 and D543N, through polymerase chain reaction restriction fragment length polymorphism (PCR RFLP) techniques. Results Two NRAMP1 polymorphisms were both significantly associated with smear positive pulmonary tuberculosis. Subjects who were heterozygous for polymorphisms in INT4 and D543N were related with tuberculosis. It was the cooperation of different polymorphisms of NRAMP1 that led to the susceptibility to tuberculosis. Conclusions The polymorphisms in NRAMP1 gene affect susceptibility to tuberculosis in Han people in China.
