DisGeNET user guides

The DisGeNET Web Interface

The DisGeNET web interface has been created using django framework.

In the DisGeNET Web Interface User Guide, you will find a tutorial addressing the following type of questions:

  • What genes are associated to a specific Disease?
  • How to retrieve the genes associated to several diseases at once?
  • What diseases are associated to a specific protein class ?
  • What are the variants associated to a specific disease?
  • How can I retrieve GDAs annotated with a specific evidence level?
  • How can I retrieve diseases associated to a particular variant consequence type?

The DisGeNET Cytoscape App

In the DisGeNET Cytoscape App User Guide, you will find a tutorial addressing the following type of questions:

  • How to create gene and variant-disease networks?
  • What diseases are associated to a specific gene, or variant, or lists of genes or variants ?
  • How to create networks by disease class?
  • How can I filter the GDAs with a specific evidence level?
  • How can I color the networks by disease class?
  • How can I annotate my protein-protein network with DisGeNET data?
  • How can I use the app in an automatic fashion from R or Python?

What kind of information can I find in DisGeNET?

DisGeNET contains a compilation of genes associated to diseases, that comes from different publicly available databases: the Comparative Toxicogenomics DatabaseTM (CTDTM), UniProt/SwissProt, the Cancer Genome Interpreter, Orphanet, the Mouse Genome Database (MGD), PsyGeNET, Genomics England, ClinGen, and the Rat Genome Database (RGD). The variant-disease associations in DisGeNET are annotated from ClinVar, the NHGRI-EBI GWAS Catalog, and the GWAS db. It also contains gene-disease, and variant-disease associations retrieved using text mining approaches (LHGDN and BeFree data).

How is the score for a gene-disease pair, or variant-disease pair computed?

For a seamless integration and ranking of gene-disease associations, we developed a gene-disease association score. The DisGeNET score for GDAs takes into account the number and type of sources (level of curation, organisms), and the number of publications supporting the association, while the score for the VDAs takes into account sources, and number of papers. The scores range from 0 to 1. For further details, click here .

What kind of questions can be answered with DisGeNET?

You can answer these type of questions:

  • what are the genes, and variants involved in a particular disease
  • what are the diseases associated to a particular gene
  • what are the diseases associated to a list of variants
  • what is the type of association between a particular gene and a disease
  • what are the more recent genes/variants reported as associated to a particular disease

What is meant by "association type"?

The "association type" describes the different flavors of the gene-disease relationship, which are described in the GeneDiseaseAssociation.owl. For instance, the Genetic Variation association type is used when a sequence variation is associated to the disease phenotype. This ontology was developed to achieve a seamless integration of gene-disease association data coming from different databases.

What is the disease vocabulary used for diseases?

All entries in DisGeNET are mapped to the UMLS® CUIs. The source databases use MeSH, or MIM identifiers, or disease names for disease terms.

What species are covered in DisGeNET?

DisGeNET is focused on human genes and their association to diseases. We also include gene-disease associations described in animal models (mouse, rat) and map the genes to the human orthologs.

How can I download the information in DisGeNET?

DisGeNET data can be obtained in different ways: by downloading the SQLite database, by downloading the RDF data dump, through the Cytoscape app, or by downloading the tab separated files at the Downloads page. Alternatively, you can download the results of your analysis by using the downloads button on the top right in the web interface.

What is the Panther Class associated to the genes?

We have added the Panther Class as a new gene attribute, that allows to classify the genes in classes according to their molecular function. For more information, check the PANTHER Protein Class ontology. Currently, the mappings are performed to the second level category of Panther Ontology, that is, the terms directly related to "protein class". The list of the categories, and their representation in DisGeNET data is shown in the table below.

Panther Class Name Number of genes
nucleic acid binding 1392
hydrolase 1178
transcription factor 927
enzyme modulator 904
transferase 787
