Schizophrenia is a severe psychiatric disorder with a high heritability. A single nucleotide polymorphism (SNP) rs1625579 (G/T; T is the common and presumed risk allele) within an intron of miR-137 gene has been recently suggested to contribute to the susceptibility to schizophrenia by a large-scale genome-wide association study (GWAS) in a sample of predominantly European ancestry. However, subsequent genetic association studies in Chinese population yielded inconsistent results.
A meta-analysis reporting the association between rs1625579 and schizophrenia in Chinese population was carried out, pooling 4 eligible case-control studies involving 2847 patients and 3018 controls.
This meta-analysis demonstrated a significant association between rs1625579 and schizophrenia under the allele model [T versus G, odds ratio (OR):1.20, 95% confidence interval (CI): 1.06-1.36] and the recessive model (TT versus GT+GG; OR: 1.19; 95% CI: 1.04-1.37). Additionally, a marginal significant association under the additive model (TT versus GG; OR: 1.64; 95% CI: 1.00-2.69) was observed. However, no significant association was observed under the dominant model (TT+GT versus GG; OR: 1.58; 95% CI: 0.97-2.59).
This meta-analysis suggested that the SNP rs1625579 in miR-137 gene might be involved in schizophrenia susceptibility in Chinese Han population.
精神分裂症是一种遗传性很高的严重精神疾病。最近一项针对主要为欧洲血统样本的大规模全基因组关联研究（GWAS）表明，miR-137基因内含子中的单核苷酸多态性（SNP）rs1625579（G/T；T是常见的且被认为是风险等位基因）与精神分裂症易感性有关。然而，随后在中国人群中的基因关联研究结果并不一致。
进行了一项荟萃分析，报告rs1625579与中国人群精神分裂症之间的关联，汇总了4项符合条件的病例对照研究，涉及2847例患者和3018例对照。
该荟萃分析表明，在等位基因模型（T对G，优势比（OR）：1.20，95%置信区间（CI）：1.06 - 1.36）和隐性模型（TT对GT + GG；OR：1.19；95% CI：1.04 - 1.37）下，rs1625579与精神分裂症存在显著关联。此外，在加性模型（TT对GG；OR：1.64；95% CI：1.00 - 2.69）下观察到边缘显著关联。然而，在显性模型（TT + GT对GG；OR：1.58；95% CI：0.97 - 2.59）下未观察到显著关联。
该荟萃分析表明，miR-137基因中的SNP rs1625579可能与中国汉族人群的精神分裂症易感性有关。
