Variants pathogenicity by type
Statistics on ClinVar variants can assist in determining whether a specific variant type in the CYP11B1 gene is commonly pathogenic or not.
In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.
Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

- Function
- FUNCTION: Has steroid 11-beta-hydroxylase activity. In addition to this activity, the 18 or 19-hydroxylation of steroids and the aromatization of androstendione to estrone have also been ascribed to cytochrome P450 XIB.;
- Disease
- DISEASE: Adrenal hyperplasia 4 (AH4) [MIM:202010]: A form of congenital adrenal hyperplasia, a common recessive disease due to defective synthesis of cortisol. Congenital adrenal hyperplasia is characterized by androgen excess leading to ambiguous genitalia in affected females, rapid somatic growth during childhood in both sexes with premature closure of the epiphyses and short adult stature. Four clinical types: 'salt wasting' (SW, the most severe type), 'simple virilizing' (SV, less severely affected patients), with normal aldosterone biosynthesis, 'non-classic form' or late- onset (NC or LOAH) and 'cryptic' (asymptomatic). {ECO:0000269|PubMed:16046588, ECO:0000269|PubMed:20089618, ECO:0000269|PubMed:2022736, ECO:0000269|PubMed:20331679, ECO:0000269|PubMed:20947076, ECO:0000269|PubMed:23940125, ECO:0000269|PubMed:24022297, ECO:0000269|PubMed:24536089, ECO:0000269|PubMed:24987415, ECO:0000269|PubMed:26053152, ECO:0000269|PubMed:26476331, ECO:0000269|PubMed:9302260}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Hyperaldosteronism, familial, 1 (HALD1) [MIM:103900]: A disorder characterized by hypertension, variable hyperaldosteronism, and abnormal adrenal steroid production, including 18-oxocortisol and 18-hydroxycortisol. There is significant phenotypic heterogeneity, and some individuals never develop hypertension. Note=The disease is caused by mutations affecting the gene represented in this entry. The molecular defect causing hyperaldosteronism familial 1 is an anti-Lepore-type fusion of the CYP11B1 and CYP11B2 genes. The hybrid gene has the promoting part of CYP11B1, ACTH-sensitive, and the coding part of CYP11B2.;
