Model description

The locus-to-gene (L2G) model derives features to prioritise likely causal genes at each GWAS locus based on genetic and functional genomics features. The main categories of predictive features are:

    - Distance: (from credible set variants to gene)
    - Molecular QTL Colocalization
    - Variant Pathogenicity: (from VEP)

How to Get Started with the Model

To use the model, you can load it using the LocusToGeneModel.load_from_hub method. This will return a LocusToGeneModel object that can be used to make predictions on a feature matrix. The model can then be used to make predictions using the predict method.
