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.

Pathogenic, criteria provided, single submitter	clinical testing	Neuberg Centre For Genomic Medicine, NCGM	-	The missense variant p.R143W in CYP11B1 (NM_000497.4) has been previously reported in affected patients (Mooji CF et al). Functional studies show a damaging effect (Menabo S et al). The variant has been submitted to ClinVar as Likely Pathogenic.In silico tools predict a damaging effect and the residue is conserved across species. For these reasons, this variant has been classified as Pathogenic -

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 143 of the CYP11B1 protein (p.Arg143Trp). This variant is present in population databases (rs140336749, gnomAD 0.1%). This missense change has been observed in individuals with clinical features of adrenal hyperplasia (PMID: 23940125, 24022297, 26053152). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 56831). 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) has been performed at Invitae 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 CYP11B1 protein function. Experimental studies have shown that this missense change affects CYP11B1 function (PMID: 23940125). For these reasons, this variant has been classified as Pathogenic. -
