Welcome to DeMAG web server!
We present DeMAG (Deciphering Mutations in Actionable Genes) a supervised and specialized VEP (Variant Effect Predictor) to interpret any missense mutations in 59 actionable genes (ACMG SF v2.0 genes).
DeMAG web server allows scientists, health professionals or anyone curious to:
- access and download predictions for all ~1.3 million missense mutations for the ACMG SF v2.0 genes (ACMG59 genes),
- investigate the features of the model for any mutation to better understand DeMAG's pathogenicity score,
- download the high-quality training set to fully reproduce our results,
- download the validation sets we used to benchmark DeMAG against popular VEPs (REVEL, EVE, …).
DeMAG is a joint collaboration between the Max Planck Insitute of Molecular Cell Biology and Genetics (MPI-CBG) and Harvard Medical School (HMS). You can read our paper on Nature Communications:

Variants with a pathogenicity probability greater or equal than 0.5 are predicted as pathogenic
The plot shows all missense substitutions for the selected gene. The black dot indicates the selected mutation
The violinplots show the distribution of the selected features for the benign and pathogenic class as in our training set. The white line corresponds to the specific variant's feature-value.

We benchamrked DeMAG on clinical, functional and population data. The clinical and functional data can be found below, while the population data will be available on request. The population data refers to putatively benign common variants from the Estonia Biobank and as it is not public yet we can't upload the data on web server. Please refer to the methods section of the manuscript for a detailed description of the analysis of the testing set.
