Welcome to HGVA project!

Human Genomic Variation Archive (HGVA) is an open-access genomic variation resource that integrates variants from the main reference human projects. HGVA also adds valuable information such as variant annotation: consequence types, population frequencies, protein effect predictions, variant-associated phenotype, etc.

Overview

HGVA aims to provide a high-performance and scalable resource to store, query and visualise variants from main open-access human datasets. We have put special emphasis on making HGVA very responsive even with complex queries and to make the data available to researchers and bioinformaticians in three different ways: a rich web interface based on OpenCB IVA, client libs (Python, Java and JavaScript) and through a command-line. Also, different datasets are normalised and annotated using OpenCB CellBase.

HGVA does not intend to replace or provide full archiving services like NCBI dbSNP or EMBL-EBI EVA projects, these provide excellent submission and accessioning services and play a crucial role allowing scientists to submit variation data for many different species. Instead, HGVA is focused on human and the most relevant datasets are selected and indexed. HGVA provides different high-performance user interfaces to allow researchers to query and visualise human datasets or to use this data in genomic pipelines.

We would like to thank very much the authors of the different projects such as 1000 Genomes Project or ExAC (see below for a complete list) for making all these invaluable data open and freely accessible for the biomedical community, we hope HGVA will help to make all these data more accessible to them.

HGVA was born during 2016 as a response to the necessity of having most relevant human datasets centralised, normalised and annotated for different analysis pipelines. It is currently developed and maintained by researchers at University of Cambridge and Genomics England and it is freely available at http://hgva.opencb.org

Main Features

  • Most important high-quality variant studies normalised and integrated in just one server database
  • Rich variant annotation performed, including HPO terms, consequence types, substitution effect prediction scores, Gene Ontology terms, etc.
  • Population frequencies calculated, including populations and super-populations
  • Interactive web-based data mining tool based on IVA
  • Clients in Python, Java, JavaScript for fast programmatic access
