Phenotype imputation
Web16. nov 2024 · The BOLT-LMM algorithm computes statistics for testing association between phenotype and genotypes using a linear mixed model (LMM) [1]. By default, BOLT-LMM assumes a Bayesian mixture-of-normals prior for the random effect attributed to SNPs other than the one being tested. This model generalizes the Web19. jan 2024 · Using these imputed phenotypes in 392,535 participants yielded hundreds of genome-wide significant associations, six of which replicate in independent cohorts.

WebPhenotype Imputation Method We consider two phenotype datasets in which we collected ℓ phenotypes from n1 and n2 individuals, respectively. Let Y(1) and Y(2) be matrices of phenotypic values of size (n1 × ℓ) and (n2 × ℓ), and y ( 1) k and y ( 2) k be vectors of phenotypic values for the kth phenotype in the first and second datasets, respectively. Web29. mar 2024 · Multiple phenotypes. Named categorical phenotypes (a phenotype string which doesn't start with a number is interpreted as a category name). See the draft specification for more details. With --pfile, you can use the ' vzs ' modifier to tell PLINK to look for prefix.pvar .zst instead of a plain .pvar file.

WebHere, we first demonstrate that heterogeneity (e.g., of sample size, phenotyping, imputation) hurts calibration of meta-analysis fine-mapping. We propose a summary statistics-based quality-control (QC) method, suspicious loci analysis of meta-analysis summary statistics (SLALOM), that identifies suspicious loci for meta-analysis fine-mapping by ...
