The paper examines sex-specific links between education-related genetic factors and fertility, finding stronger negative associations in women and weaker or positive associations in men, independent of educational attainment.

This study identifies 1,257 genetic variants associated with human personality traits using large-scale GWAS and finds widespread genetic correlations with behaviors and life outcomes.

This study performs a multi-ancestral GWAS of DSM-defined nicotine dependence, finding genetic correlations with other substance use disorders and health traits, and identifying a strong general addiction liability factor.

Family-based GWAS meta-analysis of 34 phenotypes shows standard GWAS effects carry sizeable confounding uncorrelated with direct genetic effects, while assortative mating likely inflates SNP heritability and genetic correlations.

This study identifies genetic variants associated with income and shows they correlate with health outcomes and educational attainment.

The paper uses structural equation modeling on UK Biobank data to investigate the genetic basis of neuroticism, finding that significant variants are associated with brain-expressed genes and fear-related behaviors in mice.
