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:Partial absence of toe

Accession:HP:0011305 term browser browse the term
Definition:The absence of a phalangeal segment of a toe or hallux.
Comment:The part that is absent may be specified. The "distal" modifier specifies the loss of the distal phalanx; clinically this is defined by the absence of the nail. The "proximal" modifier specifies the loss of the proximal or middle phalanx with the nail still present. It may be difficult to know which phalanx is absent without X-rays and even then, the missing bone may not be identified (note no attempt is made to distinguish missing middle from proximal phalanges). In this situation the location adjective should be removed. Note that this finding is distinct from Short toes, (which are reduced in length but have the normal number of phalangeal segments). Partial absence of the hallux is an alternative term that may be used for the first toe.
Synonyms:exact_synonym: Hypophalangy of toes
