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
    - Chromatin Interaction: (e.g., promoter-capture Hi-C)
    - 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.

Inference Examples
This model does not have enough activity to be deployed to Inference API (serverless) yet. Increase its social visibility and check back later, or deploy to Inference Endpoints (dedicated) instead.
