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 inability to maintain postures or positions (such as keeping eyes closed, protruding the tongue, maintaining conjugate gaze steadily in a fixed direction, or making a prolonged 'ah' sound) without repeated prompts.
Comment:Damage to premotor and prefrontal regions results in motor-intentional disorders that disrupt initiation, maintenance, and termination of volitional movements. Motor impersistence (i.e., failure to maintain movement) more frequently develops following right than left hemisphere lesions. {xref="PMID:17353476", xref="DOI:10.1007/978-0-387-79948-3_2046", xref="https://orcid.org/0000-0002-0736-9199"}
