Human Phenotype Ontology (HPO) gene set. This set contains genes that have been annotated to the HPO term "Abnormality of the protein C anticoagulant pathway", which is defined as "An anomaly of the protein C anticoagulant pathway, which serves as a major system for controlling thrombosis, limiting inflammatory responses, and potentially decreasing endothelial cell apoptosis in response to inflammatory cytokines and ischemia. A natural anticoagulant system denoted the protein C pathway exerts its anticoagulant effect by regulating the activity of FVIIIa and FVa. The vitamin K-dependent protein C is the key component of the pathway. Activated protein C (APC) cleaves and inhibits coagulation cofactors FVIIIa and FVa, which result in downregulation of the activity of the coagulation system. The endothelial protein C receptor stimulates the T-TM-mediated activation of protein C on the endothelial cell surface. The two cofactors, protein S and the intact form of FV, enhance the anticoagulant activity of APC." This gene set was automatically constructed using annotation and ontology data provided by HPO and includes gene-phenotypes annotations from all HPO sources. The transitive closure of this term is taken into account using is_a relationships. For more information: The Human Phenotype Ontology Consortium (HPOC), http://human-phenotype-ontology.org This gene set was generated using the GeneWeaver HPO loader v. 0.1.5, HPO OBO v. hp/releases/2020-03-27, and HPO Genes to Phenotypes (all sources, all frequencies) v. 2020.05.06.

The Human Phenotype Ontology (HPO) project, available at http://www.human-phenotype-ontology.org, provides a structured, comprehensive and well-defined set of 10,088 classes (terms) describing human phenotypic abnormalities and 13,326 subclass relations between the HPO classes. In addition we have developed logical definitions for 46% of all HPO classes using terms from ontologies for anatomy, cell types, function, embryology, pathology and other domains. This allows interoperability with several resources, especially those containing phenotype information on model organisms such as mouse and zebrafish. Here we describe the updated HPO database, which provides annotations of 7,278 human hereditary syndromes listed in OMIM, Orphanet and DECIPHER to classes of the HPO. Various meta-attributes such as frequency, references and negations are associated with each annotation. Several large-scale projects worldwide utilize the HPO for describing phenotype information in their datasets. We have therefore generated equivalence mappings to other phenotype vocabularies such as LDDB, Orphanet, MedDRA, UMLS and phenoDB, allowing integration of existing datasets and interoperability with multiple biomedical resources. We have created various ways to access the HPO database content using flat files, a MySQL database, and Web-based tools. All data and documentation on the HPO project can be found online.
