Abstract:
:The 11 beta-hydroxysteroid dehydrogenase type II enzyme (11 beta HSD2) converts cortisol into mineralocorticoid receptor inactive cortisone, thus preventing occupation of the non-selective mineralocorticoid receptor by glucocorticoids in the kidney. Mutations generating inactive enzymes have been described in the HSD11B2 gene in the congenital syndrome of apparent mineralocorticoid excess (AME), although proof of mutant protein synthesis was not provided. In the present study we have examined the metabolism of cortisol in mammalian cells transfected with plasmids expressing the wild type and mutant enzymes from three additional families of patients with mutations in the HSD11B2 gene. These studies revealed that the mutants were enzymatically inactive in intact mammalian cells expressing significant levels of both full length and truncated proteins. This is the first study to definitively show that point mutations in the HSD11B2 gene abolish 11 beta HSD2 enzymatic activity in the syndrome of AME.
