Genes affected

HSD11B2 (HGNC:5209): (hydroxysteroid 11-beta dehydrogenase 2) There are at least two isozymes of the corticosteroid 11-beta-dehydrogenase, a microsomal enzyme complex responsible for the interconversion of cortisol and cortisone. The type I isozyme has both 11-beta-dehydrogenase (cortisol to cortisone) and 11-oxoreductase (cortisone to cortisol) activities. The type II isozyme, encoded by this gene, has only 11-beta-dehydrogenase activity. In aldosterone-selective epithelial tissues such as the kidney, the type II isozyme catalyzes the glucocorticoid cortisol to the inactive metabolite cortisone, thus preventing illicit activation of the mineralocorticoid receptor. In tissues that do not express the mineralocorticoid receptor, such as the placenta and testis, it protects cells from the growth-inhibiting and/or pro-apoptotic effects of cortisol, particularly during embryonic development. Mutations in this gene cause the syndrome of apparent mineralocorticoid excess and hypertension. [provided by RefSeq, Feb 2010]

Collection Method:clinical testing

This sequence change falls in intron 3 of the HSD11B2 gene. It does not directly change the encoded amino acid sequence of the HSD11B2 protein. This variant is present in population databases (rs376023420, gnomAD 0.05%). This variant has been observed in individual(s) with apparent mineralocorticoid excess (PMID: 7670488, 10523339, 12788846). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is also known as intron 3 nt 14 C>T. ClinVar contains an entry for this variant (Variation ID: 31130). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
