Welcome to the GNAT

Genetic Network Analysis Tool lets you instantly search and visualize human genetic networks. Our networks are inferred from GTEx data, and contain:


Emma Pierson, The GTEx Consortium, Daphne Koller, Alexis Battle*, Sara Mostafavi*. “Sharing and specificity of co-expression networks across 35 human tissues.” PLOS Computational Biology. April 2015. [Paper]

*co-senior authors

You can view the genetic networks we have identified using your web browser. There are three ways of starting your exploration:

Gene-tissue network

Visualize the network for a particular gene in a particular tissue.

Explore gene networks »

Frequently-linked genes

See which genes a particular gene is most frequently linked to across tissues.

Explore frequent links »

Enriched clusters

Search all enriched clusters in a tissue and view networks of genes in each cluster.
