Variant summary

Our verdict is Pathogenic. Variant got 16 ACMG points: 16P and 0B. PM1PM5PP3_StrongPP5_Very_Strong

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 Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R374Q) has been classified as Likely pathogenic.

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.

CYP11B1 links:

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

Likely pathogenic, criteria provided, single submitter	clinical testing	3billion	May 22, 2022	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. -
