Abstract

Congenital adrenal hyperplasias (CAH) are inherited defects of cortisol biosynthesis. More than 90% of CAH are caused by 21-hydroxylase deficiency (21-OHD), found in 1:10 000 to 1:15 000 live births. Females with 'classical' 21-OHD, being exposed to excess androgens prenatally, are born with virilized external genitalia. Potentially lethal adrenal insufficiency is characteristic of two-thirds to three-quarters of patients with the classical salt wasting (SW) form of 21-OHD. Non-SW 21-OHD may be diagnosed on genital ambiguity in affected females, and/or later on the occurrence of androgen excess in both sexes. Non-classical 21-OHD, detected in > or =1:100 of certain populations, may present as precocious pubarche in children or polycystic ovarian syndrome in young women. 21-OHD is caused by mutations in the CYP21 gene encoding the steroid 21-hydroxylase enzyme. More than 90% of these mutations result from intergenic recombination between CYP21 and the closely linked CYP21P pseudogene. The degree to which each mutation compromises enzymatic activity is strongly correlated with the clinical severity of the disorder. This close association between genotype and phenotype makes it possible to predict clinical outcome in affected subjects. The risk of SW and prenatal virilization can be estimated, and overtreatment can be avoided in mildly affected cases. Glucocorticoid and mineralocorticoid replacement therapies are the mainstays of treatment, but additional therapies are being developed. A first trimester prenatal diagnosis should be proposed in families in whom molecular studies have been performed previously. The state of heterozygotism can be predicted by hormonal testing and confirmed by molecular studies. Prenatal diagnosis by direct mutation detection in previously genotyped families permits prenatal treatment of affected females in order to avoid or minimize genital virilization. Neonatal screening by hormonal methods identifies affected children before SW crises develop, reducing mortality in this disorder.

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.
