Graphical analysis for phenome-wide causal discovery in genotyped population-scale biobanks
Mendelian randomization is a popular method to detect causal relationships between traits, but can be confounded by instances of horizontal pleiotropy. Here, the authors present a Mendelian randomization workflow which includes causal discovery analysis ...

Abstract Rodent models of epilepsy remain the cornerstone of research into the mechanisms underlying genetic epilepsy. Reproducibility of experiments using these rodent models, occurring across a diversity of laboratories and commercial vendors, remains an issue impacting the cost‐effectiveness and scientific rigor of the studies performed.

Smoking and stroke: A mendelian randomization study [PDF]
We used the Mendelian randomization design to explore the potential causal association of smoking with ischemic stroke and intracerebral hemorrhage using summary statistics data for 34,217 ischemic stroke cases and 404,630 noncases, and 1,545 cases of intracerebral hemorrhage and 1,481 noncases.

Depression and Osteoporosis: A Mendelian Randomization Study [PDF]
AbstractObservational studies suggest a link between depression and osteoporosis, but these may be subject to confounding and reverse causality. In this two-sample Mendelian randomization analysis, we included the large meta-analysis of genome-wide association studies for depression among 807,553 individuals (246,363 cases and 561,190 controls) of ...

Mendelian randomization and pleiotropy analysis
BackgroundMendelian randomization (MR) analysis has become popular in inferring and estimating the causality of an exposure on an outcome due to the success of genome wide association studies. Many statistical approaches have been developed and each of these methods require specific assumptions.ResultsIn this article, we review the pros and cons of ...
