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:Abnormal increased number of megaloblasts in the bone marrow.
Comment:A megaloblast is an abnormally large nucleated red blood cell found especially in people with pernicious anemia. Megaloblasts, like their normal counterparts, normoblasts, are immature red cell precursors in the bone marrow. Megaloblasts display both a larger size than normoblasts as well as a fine reticular nuclear structure.
Synonyms:xref: SNOMEDCT_US:167921008;   UMLS:C0238801
