Trait: Barrett's esophagus

Experimental Factor Ontology (EFO) Information
Identifier EFO_0000280
Description Esophageal lesion lined with columnar metaplastic epithelium which is flat or villiform. Barrett epithelium is characterized by two different types of cells: goblet cells and columnar cells. The symptomatology of Barrett esophagus is that of gastro-esophageal reflux. It is the precursor of most esophageal adenocarcinomas. (WHO) [NCIT: C2891]
