WebApr 26, 2024 · Introduction. Mendelian randomization (MR) is an instrumental variable approach to investigate the causal effect of an exposure on an outcome by using genetic variants, typically single nucleotide polymorphisms (SNPs), as instruments for the exposure 1; the causal effect is indirectly estimated from the gene-exposure and gene-outcome … WebMendelian randomization (MR) is a framework for assessing causal inference using cross-sectional data in combination with genetic information.
