A rare genetic developmental defect during embryogenesis disorder with characteristics of severe early-onset salt-wasting adrenal insufficiency and ambiguous/female external genitalia (irrespective of chromosomal sex) due to mutations in the CYP11A1 gene. Milder cases may present delayed onset of adrenal gland dysfunction and genitalia phenotype may range from normal male to female in individuals with 46,XY karyotype. Imaging studies reveal hypoplastic/absent adrenal glands and biochemical findings include low serum cortisol, mineralocorticoids, androgens and sodium with elevated potassium levels. Caused by heterozygous, compound heterozygous or homozygous mutation in the CYP11A1 gene on chromosome 15q23-q24.
