The International Genome Sample Resource
The 1000 Genomes Project created a catalogue of common human genetic variation, using openly consented samples from people who declared themselves to be healthy. The reference data resources generated by the project remain heavily used by the biomedical science community.
The International Genome Sample Resource (IGSR) maintains and shares the human genetic variation resources built by the 1000 Genomes Project. We also update the resources to the current reference assembly, add new data sets generated from the 1000 Genomes Project samples and add data from projects working with other openly consented samples.

Improvements to Data Portal Search
We’ve improved the search bar in the IGSR data portal. Search now does a better job of combining normal word matching with partial matching, so it is more likely to find what you expect whether you search by a full name, a shorter term, or part of an identifier.
For example, searching for the data collection “MAGE RNA-seq” now returns the files that are actually linked to that data collection, instead of a much larger mixed set of unrelated files matched through the substring “RNA”. Similarly, searching for a population such as “Toscani in Italy” now behaves more consistently, giving the same expected result as searching for “Toscani”, so you no longer need to know the exact name to get accurate results. See below.
As well as this, we have added a ‘Download the list’ button to allow download of the full file list generated by your search.
