Mendelian randomization while jointly modeling cis genetics identifies causal relationships between gene expression and lipids.
A study published in the Nature Communications journal propose an MR method, MR-link, that accounts for unobserved pleiotropy and LD by leveraging information from individual-level data, even when only one eQTL variant is present. Inference of causality between gene expression and complex traits using Mendelian randomization (MR) is confounded by pleiotropy and linkage [...]
