Web3 jun. 2024 · Author summary In this article we demonstrate that common approaches for combining direct and proxy GWAS data produce dramatic underestimates of heritability, and we introduce a novel multivariate method for recovering unbiased estimates. Applying our method to direct and proxy GWAS data for Alzheimer’s disease we obtain estimates of … Web27 mrt. 2024 · Here, we propose FactorGo, a scalable variational factor analysis model to identify and characterize pleiotropic components using biobank GWAS summary data. In extensive simulations, we observe that FactorGo outperforms the state-of-the-art (model-free) approach tSVD in capturing latent pleiotropic factors across phenotypes, while …

Single trait GWAS in the statgenGWAS package follows the approach of Kang et al. ( 2010) and related papers: For the ‘empty’ model (i.e., without any SNP in the fixed effects), we obtain REML-estimates of the variance components σ g 2 and σ e 2, which give an estimate Σ ^ of the variance-covariance matrix. cjng twitter
