Abstract

Significance: Inactivating mutations in the chromodomain helicase DNA binding protein 7 ( CHD7 ) gene causes a severe developmental disorder known as CHARGE syndrome. Recently, several missense mutations in CHD7 have been reported in isolated gonadotropin-releasing hormone (GnRH) -deficiency (IGD) patients who lack full CHARGE features. However, the precise functional consequence of these IGD-associated missense mutations on the activity of CHD7 protein is not known. This study confirms the predominance of missense CHD7 alleles in 5% of IGD patients and provides, to our knowledge, first experimental evidence that functionally compromised CHD7 missense alleles contribute to the pathogenesis of both the anosmic and normosmic forms of IGD. These results imply a preferential sensitivity for CHD7 dysfunction in the developmental ontogeny as well as neuroendocrine regulation of GnRH neurons in humans.

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.
