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:Fetal choroid plexus cysts (CPCs) are sonographically discrete, small cysts found in the choroid plexus within the lateral cerebral ventricles of the developing fetus at 14 to 24 weeks gestation. Imaging of the choroid plexus is performed in the transverse plane of the fetal head at the same level that the lateral cerebral ventricle is evaluated. The choroid plexus should be inspected bilaterally for the presence of cysts. The size of CPCs is not of clinical relevance (PMID:16100637).
Comment:There is agreement that ultrasound characteristics of CPC, such as bilaterality, size, number, complexity, and resolution, are not related to the risk of aneuploidy. However, cysts with diameters less than 5 mm may not be linked with trisomy and large cysts in excess of 10 mm may impart a higher risk.
