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:A deviation from the normal proportion of terminal to vellus hairs.
Comment:Scalp hairs comprise large terminal hairs and small vellus hairs. Terminal hairs are conspicuous and exceed 0.03 mm in diameter and 1 cm in length, and may be pigmented and medullated. Vellus hairs are inconspicuous and are 0.03 mm or less in diameter and less than 1 cm in length and lack melanin and medulla.
