Genes affected

CYP11B2 (HGNC:2592): (cytochrome P450 family 11 subfamily B member 2) This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This protein localizes to the mitochondrial inner membrane. The enzyme has steroid 18-hydroxylase activity to synthesize aldosterone and 18-oxocortisol as well as steroid 11 beta-hydroxylase activity. Mutations in this gene cause corticosterone methyl oxidase deficiency. [provided by RefSeq, Jul 2008]

GML (HGNC:4375): (glycosylphosphatidylinositol anchored molecule like) Predicted to be involved in DNA damage response, signal transduction by p53 class mediator resulting in cell cycle arrest; apoptotic process; and negative regulation of cell population proliferation. Predicted to be extrinsic component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

This sequence change replaces threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 185 of the CYP11B2 protein (p.Thr185Ile). This variant is present in population databases (rs121912978, gnomAD 0.009%). This missense change has been observed in individuals with hypoaldosteronism (PMID: 9625333, 12788848, 22565077, 22931312). ClinVar contains an entry for this variant (Variation ID: 16881). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on CYP11B2 protein function. Experimental studies have shown that this missense change affects CYP11B2 function (PMID: 12788848, 21237269). For these reasons, this variant has been classified as Pathogenic. -

The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.005%). Functional studies provide strong evidence of the variant having a damaging effect on the gene or gene product (PMID: 12788848 , 21237269). The variant has been reported to be in trans with a pathogenic variant as either compound heterozygous or homozygous in at least 2 similarly affected unrelated individuals (PMID: 12788848 , 22565077 , 22931312 , 9625333). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. -
