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:Diminution of tendon reflexes, which is an invariable sign of peripheral nerve disease.
Comment:The deep tendon reflex is a monosynaptic reflex arc with sensory and motor nerve components, but the arc is much more vulnerable to sensory nerve damage. Ankle plantar flexion is retained in all but the most severe peripheral neuropathies, and thus loss of the Achilles tendon reflex in an objective indication of a substantial sensory nerve defect.
Synonyms:exact_synonym: Absent or decreased deep tendon reflexes;   Decreased deep tendon reflexes;   Decreased tendon reflexes;   Decreased to absent deep tendon reflexes;   Decreased/absent deep tendon reflexes;   Depressed tendon reflexes;   Diminished deep tendon reflexes;   Diminished or absent deep tendon reflexes;   Diminished or absent tendon reflexes;   Hypoactive to absent deep tendon reflexes;   Impaired tendon reflexes;   Reduced/absent deep tendon reflexes;   Weak or absent deep tendon reflexes
