This is the GitHub repository to provide all information, news and updates of the EpiGraphDB pQTL MR project, which is a phenome-wide Mendelian randomization study of the plasma proteome.
epigraphdb-pqtl is a GitHub repo to provide the following information:
- news and updates of the EpiGraphDB pQTL project, and issue reporting functionality for users.
- easy to use R scripts to run MR and colocalization analysis for the pQTL MR project.
The MR and colocalization analyses results from the EpiGraphDB pQTL project have been pre-calculated and stored in the EpiGraphDB Proteome PheWAS browser.
The scripts in this repository require the following dependencies to be installed:
devtools
is required to install from github:
###install the Two sample MR package (just need do this once)
source("https://bioconductor.org/biocLite.R")
install.packages("devtools")
##to install/update the R package (once there is a )
library(devtools)
install_github("MRCIEU/TwoSampleMR")
#example of use the older version of the package
devtools::install_github("MRCIEU/[email protected]")epigraphdb-pqtl provides a simple and intuitive way to run pQTL MR analysis using the "TwoSampleMR" R package
For more information on how to run the MR analysis, please check out R script MR-pQTL-script.R
The EpiGraphDB Proteome PheWAS browser currently contains the Mendelian randomization and sensitivity analyses results for 989 proteins and 225 traits, i.e. diseases and risk factors. To start using this browser, simply type a protein or trait name into the "search" field, for example, ADAM19 or Lung cancer. The full list of proteins can be found by following the link on top of the "search" field.
