Variant summary

Our verdict is Uncertain significance. Variant got 5 ACMG points: 5P and 0B. PP3_StrongPP5

The NM_000497.4(CYP11B1):​c.1120C>T​(p.Arg374Trp) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000137 in 1,602,308 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. R374R) has been classified as Benign.

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]

Deficiency of steroid 11-beta-monooxygenase Pathogenic:2
May 22, 2022
3billion
Significance: Likely pathogenic
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: <0.001%). In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.89; 3Cnet: 0.90). Same nucleotide change resulting in same amino acid change has been previously reported to be associated with CYP11B1 related disorder (ClinVar ID: VCV000035982). The variant has been observed in at least two similarly affected unrelated individuals (SCV000052290.1). A different missense change at the same codon (p.Arg374Gln) has been reported to be associated with CYP11B1 related disorder (ClinVar ID: VCV000001174 / PMID: 8506298). Therefore, this variant is classified as likely pathogenic according to the recommendation of ACMG/AMP guideline. -

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 374 of the CYP11B1 protein (p.Arg374Trp). This variant is present in population databases (rs61752786, gnomAD 0.007%). This missense change has been observed in individual(s) with congenital adrenal hyperplasia (PMID: 28228528; Invitae). 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: 35982). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
