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.
