What This Experiment Tests

Exploratory experiment designed to discover new patterns targeting DACT1, DAAM1, KCNJ3 in human genetic data - summary statistics. Primary outcome: causal relationships between variants, expression, and biomarkers

Description

Summary-based Mendelian randomization (SMR) analysis to establish causal relationships between genetic variants, gene expression, and biomarker levels. This analysis used GWAS summary statistics integrated with brain quantitative trait loci (QTL) data to identify putative causal mediators. The SMR approach helps distinguish between direct causal effects and linkage disequilibrium confounding, providing stronger evidence for biological causality.
