This repository contains genome-wide association study (GWAS) summary statistics for the following executive function traits: Trail Making Numeric (TMN) Trail Making Alpha Numeric (TMA) Mental Plasticity (TMD = TMA − TMN) These data are derived from the study:“Genetic landscape of adult executive function reveals a cell-type specific developmental origin.” For full methodological details, please refer to the original publication at: Summary statistics are provided for: Genes and Cognition (G&C) UK Biobank (UKB) Meta-analysis (G&C + UKB) 1.
