Multivariable Mendelian Randomization and Mediation [PDF]

Cold Spring Harbor Perspectives in Medicine, 2020
Mendelian randomization (MR) is the use of genetic variants associated with an exposure to estimate the causal effect of that exposure on an outcome. Mediation analysis is the method of decomposing the effects of an exposure on an outcome, which act directly, and those that act via mediating variables.

Systematic Mendelian randomization using the human plasma proteome to discover potential therapeutic targets for stroke

Nature Communications, 2022
Mendelian randomization can be used to mimic the effects of protein-targeting drugs in a population of individuals. Here, the authors have identified potential causal proteins for stroke in a two-sample Mendelian randomization framework, providing ...

Interpreting findings from Mendelian randomization using the MR-Egger method

European Journal of Epidemiology, 2017
Mendelian randomization-Egger (MR-Egger) is an analysis method for Mendelian randomization using summarized genetic data. MR-Egger consists of three parts: (1) a test for directional pleiotropy, (2) a test for a causal effect, and (3) an estimate of the ...

Mendelian Randomization Analysis With Multiple Genetic Variants Using Summarized Data

Genetic Epidemiology, 2013
Genome‐wide association studies, which typically report regression coefficients summarizing the associations of many genetic variants with various traits, are potentially a powerful source of data for Mendelian randomization investigations.

Investigating the causal impact of gut microbiota on glioblastoma: a bidirectional Mendelian randomization study

BMC Genomics, 2023
Background Currently, the influence of microbiota on the occurrence, progression, and treatment of cancer is a topic of considerable research interest. Therefore, based on the theory of the gut-brain axis proved by previous studies, our objective was to ...

Mendelian randomization: genetic anchors for causal inference in epidemiological studies

Human Molecular Genetics, 2014
Observational epidemiological studies are prone to confounding, reverse causation and various biases and have generated findings that have proved to be unreliable indicators of the causal effects of modifiable exposures on disease outcomes.

Potential drug targets for multiple sclerosis identified through Mendelian randomization analysis

Brain : a journal of neurology, 2023
Multiple sclerosis is a complex autoimmune disease, and several therapies for multiple sclerosis have been developed and widely used. However, existing medications for multiple sclerosis were far from satisfactory due to their failure to suppress ...

Deep coverage whole genome sequences and plasma lipoprotein(a) in individuals of European and African ancestries. [PDF]

, 2018
Lipoprotein(a), Lp(a), is a modified low-density lipoprotein particle that contains apolipoprotein(a), encoded by LPA, and is a highly heritable, causal risk factor for cardiovascular diseases that varies in concentrations across ancestries. Here, we use
