Three biallelic polymorphisms at the promoter region of the interleukin-10 (IL-10) gene have been associated with susceptibility to schizophrenia. The aim of this case-control study was to investigate the association between IL-10 (-1082) G/A gene polymorphisms and schizophrenia among Bataknese, a native tribe inhabiting the North Sumatera province in Indonesia.
A total of 194 unrelated participants (n = 97 for each case and control groups) participated in this study. Polymerase chain reaction restriction fragment length polymorphism molecular genotyping was conducted to assess the genotype and allele distribution of IL-10 (-1082 G/A).
Allele variations indicated that the dominant allele in the Batak tribe was allele A, whereas homozygous GG genotypes were not found in either group. The A allele and AA genotype were found to be risk factors for developing schizophrenia (OR = 2.26, 95% CI = 1.1825-4.3559 and OR = 2.56, 95% CI = 1.280-5.152, respectively).
Only the A allele and AA genotype of the IL-10 gene polymorphism at -1082 G/A contribute to schizophrenia susceptibility in Bataknese.
白细胞介素-10(IL-10)基因启动子区域的三个双等位基因多态性与精神分裂症易感性相关。本病例对照研究的目的是调查居住在印度尼西亚北苏门答腊省的原住民巴塔克族中IL-10(-1082)G/A基因多态性与精神分裂症之间的关联。
共有194名无亲属关系的参与者(病例组和对照组各97名)参与了本研究。采用聚合酶链反应-限制性片段长度多态性分子基因分型方法评估IL-10(-1082 G/A)的基因型和等位基因分布。
等位基因变异表明,巴塔克部落的优势等位基因为A等位基因,而两组均未发现纯合GG基因型。发现A等位基因和AA基因型是患精神分裂症的危险因素(OR分别为2.26,95%CI为1.1825 - 4.3559;OR为2.56,95%CI为1.280 - 5.152)。
在巴塔克族中,只有IL-10基因多态性-1082 G/A处的A等位基因和AA基因型与精神分裂症易感性有关。
