Another progenitor of Mendelian randomization is Sewall Wright who introduced path analysis, a form of causal diagram used for making causal inference from non-experimental data. The method relies on causal anchors, and the anchors in the majority of his examples were provided by Mendelian inheritance, as is the basis of MR. [17]
Eric Gamazon has developed computational methods that can be used to identify genes and mechanisms underlying complex diseases. [4] [5] He was a developer of the transcriptome-wide association study [6] [7] (TWAS) methodology (PrediXcan), which integrates gene expression and genome-wide association study data to identify disease-associated genes.
For these data, they used nonlinear and linear Mendelian randomization analyses, research methods used to provide evidence for causal relationships between risk factors and health outcomes.
Judea Pearl defines a causal model as an ordered triple ,, , where U is a set of exogenous variables whose values are determined by factors outside the model; V is a set of endogenous variables whose values are determined by factors within the model; and E is a set of structural equations that express the value of each endogenous variable as a function of the values of the other variables in U ...
A genetic study using Mendelian randomization analysis demonstrated that high occupation levels were associated with reduced risk for Alzheimer’s disease. In addition, this study confirmed that occupational attainment had an independent effect on the risk for Alzheimer’s disease even after taking educational attainment into account. [25]
[30] [31] The observation that genetic correlations usually mirror phenotypic correlations is known as "Cheverud's Conjecture" [32] and has been confirmed in animals [33] [34] and humans, and showed they are of similar sizes; [35] for example, in the UK Biobank, of 118 continuous human traits, only 29% of their intercorrelations have opposite ...
