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:Nuchal translucency is the sonographic appearance of subcutaneous accumulation of liquid in the back of the fetal neck in the first trimester of pregnancy (11-14 gestational weeks of pregnancy).
Comment:Increased nuchal translucency may be related to a cystic hygroma or to mesenchymal edema. Increased nuchal translucency can be classified into three categories: 1) cardiac abnormalities, combined with abnormal ductus venosus flow velocities, is found, leading to the theory that cardiac failure causes nuchal translucency enlargement; 2) various types of abnormalities are found in the extracellular matrix of the nuchal skin of fetuses with increased nuchal translucency; 3) abnormal lymphatic development is demonstrated in fetuses with increased nuchal translucency.
Synonyms:xref: UMLS:C4023676
