Abstract excerpt
The overall contribution of pleiotropy to disease architectures is unknown, as most studies estimate genetic correlations with each auxiliary disease in turn. Here we propose a method-pleiotropic shared heritability with bias correction (PHBC)-to estimate the liability-scale genetic variance of a target disease that is shared with a specific set of auxiliary diseases ( h 2 pleio ). PHBC estimates h 2 pleio from a...
