Craniofacial defects of blastogenesis: Duplication of pituitary with cleft palate and orophgaryngeal tumors
Abstract
Duplications of organs and/or tissues are rare in morphogenesis and have frequently been attributed to incomplete twinning. To further elucidate the phenotypes associated with organ duplications, we present three infants with duplication of the pituitary gland (DPG). A review of previously reported cases with DPG showed that the commonest additional findings were hypothalamic enlargement, a broad or duplicated sella, cleft palate, hypertelorism, oropharyngeal tumors, agenesis or hypoplasia of the corpus callosum, and abnormalities of vertebrae. DPG and additional malformations constitute a distinct and recognizable pattern of anomalies, which may constitute a polytopic field defect due to splitting of the notochord. However, the precise inductive mechanism resulting in DPG remains unknown. © 2005 Wiley‐Liss, Inc.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
