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:Hydrocephalus is an active distension of the ventricular system of the brain resulting from inadequate passage of CSF from its point of production within the cerebral ventricles to its point of absorption into the systemic circulation.
Comment:Hydrocephalus results from an imbalance between the rate of production of cerebrospinal fluid (CSF), mainly in the choroid plexus, and its reabsorption in the subarchnoid space over brain and spinal cord.
Synonyms:exact_synonym: Hydrocephaly;   Nonsyndromal hydrocephalus;   Too much cerebrospinal fluid in the brain
