Characterizing substructure via mixture modeling in large-scale genetic summary statistics

Hayley R Stoneman,

Abstract: Genetic summary data are both broadly accessible and highly useful including for risk prediction, causal inference, fine mapping, and the incorporation of external controls. Nevertheless, collapsing individual-level data into groups masks intra- and inter-sample heterogeneity (e.g., population structure), leading to confounding, reduced power, and bias. Unaccounted for substructure limits summary data usability, especially for understudied or admixed populations. Here, we present Summix2, a comprehensive set o… Show more
