Additional Information:

Description: (OMIM) Apparent mineralocorticoid excess (AME) is an autosomal recessive form of low-renin hypertension associated with low aldosterone, metabolic alkalosis, hypernatremia, and hypokalemia. The disorder is due to a congenital defect in 11-beta-hydroxysteroid dehydrogenase type II (HSD11B2) activity, resulting in ...
Clinical Description OMIM Werder et al. (1974) reported a 3-year-old girl with low birth weight, short stature, polydipsia, polyuria, and hypertension in the absence of genital anomalies. Laboratory studies showed hypernatremia, hypokalemia, metabolic alkalosis, and suppressed renin and aldosterone. Urinary steroid ...
Genotype-Phenotype Correlations OMIM Nunez et al. (1999) identified 4 novel and 3 previously reported HSD11B2 mutations in 4 patients with AME. Transfection experiments showed that 2 of the mutations abolished activity in whole cells, but that 3 others retained significant activity. ...
Molecular genetics OMIM In 9 patients from 8 families with apparent mineralocorticoid excess and hypertension, Mune et al. (1995) identified 7 different mutations in the HSD11B2 gene (see, e.g., 614232.0001 and 614232.0002). All patients were homozygous or compound heterozygous for the ...
