Welcome to openSNP

Upload Your Genotyping File

Upload the raw genotyping or exome data you got from 23andMe, deCODEme or FamilyTreeDNA to the database of openSNP 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 as many phenotypes, characteristics and traits with other openSNP users and find others with similar characteristics.
Maybe you will help scientists discover new genetic associations!

Share your stories on variations & phenotypes

openSNP lets you share your stories on your genetic variations and phenotypes with others. Discover the stories of other users.
Find others to exchange experiences about your variations.

Find literature on genetic variation

openSNP gets the latest open access journal articles on genetic variations via the Public Library of Science. Additionally popular articles are indexed via the social reference manager Mendeley. 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 find genetic markers. Easily find people with the variation you are interested in via openSNP.

The variation you are looking for is not entered yet? Just add it to openSNP

Easily download datasets

The mass download-function of openSNP allows you to easily download the 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 is easy to get datasets that are already usable for association studies.

Get notified about new data

openSNP delivers a 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 all data junkies that need more data: There is also a feed that carries all new datasets.
