Variant summary
Our verdict is Likely pathogenic. Variant got 9 ACMG points: 9P and 0B. PM2PM5PP3_StrongPP5
The NM_000497.4(CYP11B1):c.346T>G(p.Trp116Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000342 in 1,461,892 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. W116C) has been classified as Likely pathogenic.

Experimental studies have shown that this variant affects CYP11B1 protein function (PMID: 20089618). This sequence change replaces tryptophan with glycine at codon 116 of the CYP11B1 protein (p.Trp116Gly). The tryptophan residue is highly conserved and there is a large physicochemical difference between tryptophan and glycine. This variant is present in population databases (rs772733691, ExAC 0.001%). This variant has been observed in individual(s) with adrenal hyperplasia (PMID: 20089618). ClinVar contains an entry for this variant (Variation ID: 553208). 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 variant disrupts the p.Trp116 amino acid residue in CYP11B1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 15755848, 18204274, 28228528). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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. -
Deficiency of steroid 11-beta-monooxygenase Uncertain:1
- -
Glucocorticoid-remediable aldosteronism Uncertain:1
This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
