Human Phenotype Ontology (HPO)

Published by National Human Genome Research Institute (NHGRI) | U.S. Department of Health & Human Services | Catalog Last Checked: September 28, 2026 at 08:25 PM
The Human Phenotype Ontology (HPO) project provides an ontology of medically relevant phenotypes, disease-phenotype annotations, and the algorithms that operate on these. The HPO can be used to support differential diagnostics, translational research, and a number of applications in computational biology by providing the means to compute over the clinical phenotype. The HPO is being used for computational deep phenotyping and precision medicine as well as integration of clinical data into translational research.
