Description : Congenital adrenal hypoplasia (AHC) is a rare disorder that can be inherited in an
X-linked or autosomal recessive (see 240200) pattern. In X-linked AHC, primary adrenocortical
failure occurs because the adrenal glands lack the permanent adult cortical zone.
The remaining cells are termed 'cytomegalic' because they are larger than typical
fetal adrenal cells (Hay et al., 1981; Reutens et al., 1999). A contiguous gene syndrome
involving a combination of congenital adrenal hypoplasia, glycerol kinase deficiency
(307030), and Duchenne muscular dystrophy (DMD; 310200) is caused by deletion of multiple
genes on chromosome Xp21 (see 300679).;
Inheritance : X-linked recessive;
Molecular basis : Caused by mutation in the nuclear receptor subfamily 0, group B, member 1 gene (NR0B1,
300473.0001);
Laboratory abnormalities : Hyponatremia; Decreased serum cortisol; Decreased serum follicle-stimulating hormone (FSH); Decreased serum luteinizing hormone (LH); Decreased serum androgens; Decreased serum testosterone; Increased adrenocorticotropic hormone (ACTH);
