A genetic association between the fibroblast growth factor 20 (FGF20) gene and Parkinson's disease has been found by the pedigree disequilibrium test. This association, however, was not replicated by a case-control association study. In order to clarify the association between the FGF20 gene and Parkinson's disease, we attempted to replicate this association by a case-control association study using a large number of Japanese samples (1388 patients and 1891 controls). rs1721100 exhibited a significant difference in allele C versus G (P=0.0089), and in genotype CC+CG versus GG (P=0.0053). Haplotype association analysis showed that haplotype 2 was the protective haplotype for Parkinson's disease (permutation-P=0.0075). These results suggest that the FGF20 gene is a susceptibility gene for Parkinson's disease in the Japanese population.
通过系谱不平衡检验发现了成纤维细胞生长因子20（FGF20）基因与帕金森病之间的遗传关联。然而，该关联在病例对照关联研究中未得到重复验证。为了阐明FGF20基因与帕金森病之间的关联，我们尝试通过使用大量日本样本（1388例患者和1891例对照）的病例对照关联研究来重复这一关联。rs1721100在等位基因C与G之间显示出显著差异（P = 0.0089），在基因型CC + CG与GG之间也有显著差异（P = 0.0053）。单倍型关联分析表明，单倍型2是帕金森病的保护性单倍型（置换P = 0.0075）。这些结果表明，FGF20基因是日本人群中帕金森病的一个易感基因。
