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:Aplasia/Hypoplasia of the proximal phalanx of the thumb
go back to main search page
Accession:HP:0009629 term browser browse the term
Definition:This term applies if the proximal phalanx of the thumb is either small/hypoplastic or absent. In contrast to the proximal phalanges of the digits 2-5, the proximal phalanx of the thumb is embryologically equivalent to the middle phalanges of the other digits, whereas the first metacarpal is embryologically of phalangeal origin and as such equivalent to the proximal phalanges of the other digits.
Synonyms:exact_synonym: Absent/small innermost thumb bone;   Absent/underdeveloped innermost thumb bone
 xref: UMLS:C4024268
