Magnetic resonance imaging and circulating molecular testing are potential methods for diagnosing and treating Parkinson's disease (PD). However, their relationships remain insufficiently studied. Using genome-wide association summary statistics, we found in the general population a genetic negative correlation between white matter tract mean diffusivity and PD (-0.17 < Rg < -0.11, p < 0.05), and a positive correlation with intracellular volume fraction (0.12 < Rg < 0.2, p < 0.05). Additionally, 1345 circulating genes causally linked with white matter tract diffusivity were enriched for muscle physiological abnormalities (padj < 0.05). Notable genes, including LRRC37A4P (effect size = 15.7, p = 1.23E-55) and KANSL1-AS1 (effect size = -15.3, p = 1.13E-52), were directly associated with PD. Moreover, 23 genes were found linked with genetically correlated PD-IDP pairs (PPH4 > 0.8), including SH2B1 and TRIM10. Our study bridges the gap between molecular genetics, neuroimaging, and PD pathology, and suggests novel targets for diagnosis and treatment.
磁共振成像和循环分子检测是诊断和治疗帕金森病（PD）的潜在方法。然而，它们之间的关系仍未得到充分研究。利用全基因组关联汇总统计数据，我们在普通人群中发现白质束平均扩散率与PD之间存在遗传负相关（-0.17 < Rg < -0.11，p < 0.05），与细胞内体积分数呈正相关（0.12 < Rg < 0.2，p < 0.05）。此外，1345个与白质束扩散率有因果联系的循环基因在肌肉生理异常方面富集（padj < 0.05）。包括LRRC37A4P（效应大小 = 15.7，p = 1.23E-55）和KANSL1-AS1（效应大小 = -15.3，p = 1.13E-52）在内的显著基因与PD直接相关。此外，发现23个基因与遗传相关的PD-影像诊断参数对有关联（PPH4 > 0.8），包括SH2B1和TRIM10。我们的研究填补了分子遗传学、神经影像学和PD病理学之间的空白，并提出了新的诊断和治疗靶点。
