Abstract Epilepsy, a prevalent neurodevelopmental disorder in children, is often accompanied by detrimental psychological consequences and other comorbidities. We performed exome sequencing on 963 patient-parent trios, revealing differences genetic epidemiology between Chinese European epilepsy cohorts. The diagnostic yield for known genes was 40%. Pathogenic variants were most commonly found SCN1A, KCNQ2, DEPDC5. Additionally, we identified 15 novel monogenic candidates at least two patients diagnosed with developmental epileptic encephalopathy, non-acquired focal epilepsy, or generalized including ADCY2, BCAR3, CDC45, CHRNG, CRTC2, CSMD1, CSMD2, KDM6B, KIF1B, PLEKHM3, PPP4R1, RASGRP2, SGSM2, SYNE1 , ZFHX3 . Aside from ADCY2 which implicated the GABAergic synapse pathway based KEGG analysis, these do not belong to pathways.

Depression, a widespread and highly heritable mental health condition, profoundly affects millions of individuals worldwide. Neuroimaging studies have consistently revealed volumetric abnormalities in subcortical structures associated with depression. However, the genetic underpinnings shared between depression volumes remain inadequately understood. Here, we investigate extent polygenic overlap using bivariate causal mixture model (MiXeR), leveraging summary statistics from largest genome-wide association for (N = 674,452) 14 phenotypes 33,224). Additionally, identify genomic loci through conditional/conjunctional FDR analyses. MiXeR shows that traits share substantial proportion variants depression, 44 distinct identified by subsequent conjunctional analysis. These are predominantly located intronic regions (58.7%) non-coding RNA (25.4%). The 269 protein-coding genes mapped these exhibit specific developmental trajectories, expression level 55 linked to both volumes, 30 cognitive abilities behavioral symptoms. findings highlight architecture phenotypes, enriching our understanding neurobiological Depression people authors show brain identifying loci.

While neurological and psychiatric disorders have historically been considered to reflect distinct pathogenic entities, recent findings suggest shared pathobiological mechanisms. However, the extent which these heritable share genetic influences remains unclear. Here, we performed a comprehensive analysis of GWAS data, involving nearly 1 million cases across ten diseases disorders, compare their common risk biological underpinnings. Using complementary statistical tools, demonstrate widespread overlap even in absence correlations. This indicates that large set variants impact multiple but with divergent effect sizes. Furthermore, interrogation revealed range processes associated diseases, while consistently implicated neuronal biology. Altogether, study key etiological aspects, has important implications for disease classification, precision medicine, clinical practice.

Abstract Schizophrenia (SCZ), a highly heritable mental disorder, is characterized by cognitive impairment, yet the extent of shared genetic basis between schizophrenia and performance (CP) remains poorly understood.

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.
