摘要
目的：本研究旨在利用遗传数据和孟德尔随机化（MR）分析方法探讨偏头痛与白质（WM）结构连通性之间的潜在因果关系。方法：收集偏头痛（48,975例/540,381例对照）和206个WM结构连接相关成像衍生表型（IDPs）（26,333个样本）的全基因组关联研究（GWAS）汇总统计数据。基于从GWAS汇总统计中选择的工具变量（IVs），进行双向双样本MR分析，以推断偏头痛与WM结构连通性之间的双向因果关系。反方差加权（IVW）法是分析因果关系的主要方法。结果：在正向MR分析中，发现偏头痛对右半球体运动网络到杏仁核WM结构连接有显著影响（ivw衍生β = 0.11, 95% CI = [0.04, 0.17], p = 1.002 -03, FDR p = 0.04）。而在反向MR分析中，没有发现WM结构连通性与偏头痛之间的因果关系。结论：本研究为偏头痛与WM结构连通性之间的因果关系提供了遗传学证据。这些发现为认识偏头痛的神经病理学和症状学提供了新的视角，并可能为未来偏头痛的治疗研究提供潜在的治疗靶点。
A Bidirectional Mendelian Randomization Study of Causal Relationships Between Migraine and White-Matter Structural Connectivity.
Objective: This study aims to investigate the potential causal relationship between migraine and white matter (WM) structural connectivity using genetic data and the Mendelian randomization (MR) analyses method.
Methods: Genome-wide association study (GWAS) summary statistics for migraine (48,975 cases/540,381 controls) and 206 WM structural connectivity related imaging-derived phenotypes (IDPs) (26,333 samples) were collected. Based on instrumental variables (IVs) selected from the GWAS summary statistics, the bidirectional two-sample MR analyses were conducted to infer bidirectional causal associations between migraine and WM structural connectivity. The inverse variance-weighted (IVW) method served as the primary approach for analyzing causality.
Results: In the forward MR analysis, it was found that migraine had a significant effect on right hemisphere somatomotor network to amygdala WM structural connectivity (IVW-derived β = 0.11, 95% CI = [0.04, 0.17], p = 1.02e-03, FDR p = 0.04). While in the reverse MR analysis, no causal link was detected between WM structural connectivity and migraine.
Conclusion: This study provides genetic evidences for a causal relationship between migraine and WM structural connectivity. These findings provide new perspectives for the understanding of neuropathology and symptomatology in migraine and might provide a potential therapeutic target for future migraine treatment research.
