Genes affected
CYP11B2 (HGNC:2592): (cytochrome P450 family 11 subfamily B member 2) 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. The enzyme has steroid 18-hydroxylase activity to synthesize aldosterone and 18-oxocortisol as well as steroid 11 beta-hydroxylase activity. Mutations in this gene cause corticosterone methyl oxidase deficiency. [provided by RefSeq, Jul 2008]
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]

ACMG classification

Classification made for transcript

Verdict is Pathogenic. Variant got 14 ACMG points.

PVS1
Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most 50 bp of the penultimate exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.107 CDS is truncated, and there are 3 pathogenic variants in the truncated region.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 8-142912578-G-T is Pathogenic according to our data. Variant chr8-142912578-G-T is described in ClinVar as [Pathogenic]. Clinvar id is 235237.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr8-142912578-G-T is described in Lovd as [Pathogenic].

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 21, 2023This sequence change creates a premature translational stop signal (p.Cys450*) in the CYP11B2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CYP11B2 are known to be pathogenic (PMID: 20494601, 22801770, 26936515). For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 235237). This variant has not been reported in the literature in individuals affected with CYP11B2-related conditions. This variant is not present in population databases (gnomAD no frequency). -
