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/.

Term:Duplication of the 1st metacarpal
go back to main search page
Accession:HP:0009609 term browser browse the term
Definition:Partail or complete duplication of the first metacarpal bone.
Comment:In contrast to the metacarpals 2-5, the first metacarpal is embryologically of phalangeal origin. This term applies if the first metacarpal is completely or partially duplicated. Depending on the severity, the appearance on x-ray can vary from a notched metacarpal (the duplicated bone is almost completely fused with the metacarpal), a partially fused appearance of the two bones (in most cases the fused bone resembles a Y-shape), or two separate metacarpal bones appearing side to side.
Synonyms:exact_synonym: Partial/complete duplication of the 1st long bone of hand;   Partial/complete duplication of the 1st metacarpal
 xref: UMLS:C4021426
