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:An abnormality of the thyroid gland owing to the presence of a fibrous cyst resulting from the persistence of the thyroglossal duct.
Comment:A developmental defect resulting in the presence of a thyroglossal cyst, a fibrous cyst that forms from a persistent thyroglossal duct. During the embryologic development of the thyroid gland, the precursor of the thyroid migrates from the base of the tongue inferiorly though the thyroglossal duct. This duct normally disappears following the development and migration of the thyroid gland, but if a portion of the duct remain it can form a thyroglossal cyst.
Synonyms:exact_synonym: Thyroglossal duct cyst
