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:Any abnormality of the electrical responses of various cell types in the retina as measured by electroretinography.
Comment:The electrical responses of the photoreceptors (rods and cones), inner retinal cells (bipolar and amacrine cells), and the ganglion cells can be assessed by ERG.
