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 structural anomaly of the elastic fibers of the skin. Elastic fibers are the essential extracellular matrix macromolecules comprising an elastin core surrounded by a mantle of fibrillin-rich microfibrils.
Comment:Elastic fibers help the skin return to its normal configuration after being stretched or deformed. The elastic fibers consist of two components: microfibrils and matrix elastin. The microfibrillar component amounts to only 15% of the elastic fiber, whereas the amorphous, electron-lucid elastin makes up 85% of the fiber. In light microscope sections that are routinely stained, elastic fibers are inconspicuous. With special elastic tissue stains, such as orcein or resorcin-fuchisin, or in plastic-embedded sections they are found entwined among the collagen bundles [PMID:21738362].
