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. This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 371 of the CYP11B1 protein (p.Glu371Gly). This variant is present in population databases (rs368944209, gnomAD 0.007%). This missense change has been observed in individual(s) with congenital adrenal hyperplasia due to 11-beta-hydroxylase deficiency (PMID: 8768848). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 554618). Experimental studies have shown that this missense change affects CYP11B1 function (PMID: 8768848). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -
CYP11B1-related disorder Pathogenic:1
The CYP11B1 c.1112A>G variant is predicted to result in the amino acid substitution p.Glu371Gly. This substitution was predicted to disrupt the ion pair R374-E371, which is responsible for maintaining the heme-binding site (Khattab et al. 2017. PubMed ID: 28228528). In the compound heterozygous state with a frameshift variant, this variant was reported in an individual with 11-beta-hydroxylase deficiency (Geley et al. 1996. PubMed ID: 8768848). This variant is reported in 0.0062% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/8-143957137-T-C). This variant is interpreted as likely pathogenic. -
