在帕金森病(PD)中复制第一个全基因组关联研究(GWAS)的尝试尚未成功识别遗传风险因素。本研究重新评估了GWAS的数据,并重点关注第一个PD GWAS的2级患者对照系列中P值最低的SNP(rs11155313,位于Phactr2基因中)。我们采用了四个病例对照系列来检查指定的SNP rs11155313,并在美国(OR:1.39,P=0.032),加拿大(OR:1.41,P=0.014)和爱尔兰(OR:1.44,P=0.034)患者对照系列中确定了相关性,但在挪威系列中没有(OR:1.15,P=0.27)。当合并所有四个系列时,观察到的趋势具有统计学显著性(OR:1.30,P<0.001)。这项研究表明,重新评估GWAS的公开结果可能有助于提名PD的新风险因素。
Attempts at replicating the first genome-wide association study (GWAS) in Parkinson's disease (PD) have not successfully identified genetic risk factors. The present study reevaluates data from the GWAS and focuses on the SNP (rs11155313, located in the Phactr2 gene) with the lowest P-value in the Tier 2 patient-control series of the first PD GWAS. We employed four case-control series to examine the nominated SNP rs11155313 and identified association in US (OR: 1.39, P=0.032), Canadian (OR: 1.41, P=0.014) and Irish (OR: 1.44, P=0.034) patient-control series, but not in the Norwegian series (OR: 1.15, P=0.27). When combining all four series the observed trend was statistically significant (OR: 1.30, P<0.001). This study shows reappraisal of publicly available results of GWAS may help nominate new risk factors for PD.
