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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -19 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 45 curated pathogenic missense variants (we use a threshold of 10). The gene has 9 curated benign missense variants. Gene score misZ: -1.5619 (below the threshold of 3.09). Trascript score misZ: -0.26962 (below the threshold of 3.09). GenCC associations: The gene is linked to glucocorticoid-remediable aldosteronism, congenital adrenal hyperplasia due to 11-beta-hydroxylase deficiency.

BP4

Computational evidence support a benign effect (MetaRNN=0.010213941).

BP6

Variant 8-142877064-G-C is Benign according to our data. Variant chr8-142877064-G-C is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 362165.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000427 (65/152244) while in subpopulation AMR AF = 0.00418 (64/15300). AF 95% confidence interval is 0.00336. There are 0 homozygotes in GnomAd4. There are 38 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 7 AD,AR gene
