HUMAN PHENOTYPE - ANNOTATIONS

The Human Phenotype Ontology (HPO) is downloaded weekly from http://compbio.charite.de/hudson/job/hpo/lastStableBuild/artifact/ontology/release/hp.obo. The file downloaded is considered the "last stable build" available for the ontology. For more about the HPO, view their website at http://www.human-phenotype-ontology.org/.

Definition:With the pathergy test, a small, sterile needle is inserted into the skin of the forearm. The site of injectionis circuled and observed after one and two days. If a small red bump or pustule at the site of needle insertion occurs, the pathergy test is considered to have a positive (abnormal) result.
Comment:A positive pathergy test indicates the immune system is overreacting to a minor injury. A positive test result can be seen in Behcet disease and other conditions.
