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:The presence of high titers of antigen-precipitating IgG in the serum.
Comment:Sensitization to inhaled antigens may cause high titers of antigen-precipitating IgGs. Precipitins support the diagnosis of hypersensitivity pneumonitis, also known as extrinsic allergic, in symptomatic individuals. They may also be found in asymptomatic individuals, indicating exposure to a certain antigen. Major antigens causing hypersensitivity pneumonitis are mushrooms, fungi, yeasts, bird proteins, certains chemicals, bacteria or mycobacteria.
Synonyms:exact_synonym: Increased level of antigen-precipitating IgG antibodies
