Genes affected

CYP11B1 (HGNC:2591): (cytochrome P450 family 11 subfamily B member 1) 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 and is involved in the conversion of progesterone to cortisol in the adrenal cortex. Mutations in this gene cause congenital adrenal hyperplasia due to 11-beta-hydroxylase deficiency. Transcript variants encoding different isoforms have been noted for this gene.

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 arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 384 of the CYP11B1 protein (p.Arg384Gln). This variant is present in population databases (rs764598023, gnomAD 0.0009%). This missense change has been observed in individuals with 11-beta-hydroxylase deficiency (PMID: 8506298, 15751602, 20089618, 26956189). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 552238). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt CYP11B1 protein function with a positive predictive value of 95%. Experimental studies have shown that this missense change affects CYP11B1 function (PMID: 8506298). For these reasons, this variant has been classified as Pathogenic. -

Identified in an individual with clinical and biochemical features of 11 beta-hydroxylase deficiency in published literature (Curnow et al., 1993); Functional studies demonstrate a damaging effect (impaired function of CYP11B1 resulting in disrupted enzymatic activity) (Curnow et al., 1993); Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 8506298) -
