PhenoScanner is a curated database holding publicly available results from large-scale genome-wide association studies. The motivation for creating this tool is to facilitate “phenome scans”, the cross-referencing of genetic variants with a broad range of phenotypes, to help aid the understanding of disease pathways and biology.

The catalogue currently contains over 65 billion associations and over 150 million unique genetic variants. The results are aligned across traits to the same effect and non-effect alleles for each genetic variant. PhenoScanner can perform queries on genetic variants, genes (p < 1E-5), genomic regions (p < 1E-5) and traits (p < 1E-5).

Terms of use

If you use PhenoScanner you agree to the following terms:

  • You will cite both our papers in any publication or presentation where you use results from PhenoScanner (see citations above).
  • You will cite the original paper where the results were obtained, including the references for the linkage disequilibrium statistics and variant & phenotype mappings where used (table of studies).
  • You will follow any additional terms and conditions of the underlying data (table of studies).



PhenoScanner imposes no restrictions on access to, or use of, the data provided and the software used to present it. The data generated by members of the project are available without restriction.
