Welcome to openSNP


openSNP lets customers of direct-to-customer genetic tests publish their test results, find others with similar genetic variations, learn more about their results by getting the latest primary literature on their variations, and helps scientists find new associations.

Sign Up! Download the data!

Upload Your Genotyping File

Upload your raw genotyping or exome data from 23andMe, deCODEme or FamilyTreeDNA to the openSNP database to make it available for everybody.

Share Your Phenotypes & Traits

Phenotypes are the observable characteristics of your body, such as height, eye color or preference for coffee. Share your phenotype with other openSNP users, and find others with similar characteristics and traits.
Your data may help scientists discover new genetic associations!

Share your stories on variations & phenotypes

With openSNP you can share stories about your genetic variations and phenotypes, and discover the stories of other users.

Find literature on genetic variation

openSNP gets the latest open access journal articles on genetic variations from the Public Library of Science. Popular articles are indexed via the social reference manager Mendeley, and summaries are provided by SNPedia.

Search for phenotypes

Many diseases and traits are suspected to have genetical components. Genome Wide Association Studies are a simple tool for finding genetic markers. Easily find people with the variation you are interested in via openSNP.

Is the variation for which you're looking not entered yet? Just add it to openSNP.

Easily download datasets

The mass-download function of openSNP allows you to easily download full genotyping raw-data in the file formats that are provided by 23andMe, deCODEme and FamilyTreeDNA.

As the files can be grouped by their variations for specific phenotypes, it's easy to get datasets that are already usable for association studies.

Get notified about new data

openSNP delivers an RSS feed for each phenotype. So you can easily get all new datasets that get available for the phenotypes of your interest, without the need to check for new entries by hand.

For data-junkies that need more data: there's also a feed that carries all new datasets.
