Depression, a complex and heritable psychiatric disorder, is associated with alterations in white matter microstructure, yet their shared genetic basis remains largely unclear. Utilizing the largest available genome-wide association study (GWAS) datasets for depression (N = 674,452) microstructure 33,224), assessed through diffusion tensor imaging metrics such as fractional anisotropy (FA) mean diffusivity (MD), we employed linkage disequilibrium score regression method to estimate global correlations, local analysis of [co]variant approach pinpoint genomic regions conjunctional false discovery rate identify variants. Our findings revealed that showed significant correlations FA 37 MD 59 regions, while were weak. Variant-level identified 78 distinct loci jointly (25 novel loci) (35 loci), 41 (17 loci). Further analyses these exhibited both concordant discordant effect directions between traits, well overlapping hemispheric patterns architecture. Enrichment implicated biological processes related metabolism regulation. This provides evidence mixed-direction architecture microstructure. The identification specific pathways offers potential insights developing targeted interventions improve integrity alleviate depressive symptoms.

Both schizophrenia (SCZ) and Alzheimer's disease (AD) are highly heritable brain disorders. Despite of the observed comorbidity shared psychosis cognitive decline between two disorders, genetic risk architecture by SCZ AD remains largely unknown. Based on summary statistics currently available largest genome-wide association studies for (n = 130,644) 455,258) in individuals European ancestry, we conducted conditional/conjunctional false discovery rate (FDR) analysis to enhance statistical power discovering more associations with or detect common variants both We found conditioned vice versa across different levels significance, indicating polygenic overlap. 268 (78 novel) SCZ-only 125 (55 AD-only SNPs at conditional FDR < 0.01, 16 lead conjunctional 0.05. Only half showed concordant effect direction, which was consistent modest correlation (r 0.097; P 0.026) This study provides evidence overlap AD, suggesting existence molecular mechanisms, may inform therapeutic targets that applicable

Abstract Alzheimer’s disease, a common and progressive neurodegenerative disorder, is associated with alterations in hippocampal volume, as revealed by neuroimaging research. However, the causal links between volumes of hippocampus its subfield structures disease remain unknown. A genetic correlation analysis using linkage disequilibrium score regression was conducted to identify volumetric traits linked disease. Following this, examine traits, we applied two-sample Mendelian randomization approach, utilizing bidirectional framework. Seven were found genetically correlated then included analyses. Inverse variance weighted analyses that increased left whole hippocampus, body, right presubiculum head cornu ammonis 1 causally related higher risks Conversely, risk decreased body hippocampus. These results validated through other approaches sensitivity analysis. Our findings uncover relationships suggesting not only potential significance these predicting but also reciprocal influence on volumes.
