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.

Variant summary: CYP11B1 c.187G>C (p.Asp63His) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 2.4e-05 in 251400 control chromosomes.c.187G>C has been reported in the literature in at least one individual affected with Congenital Adrenal Hyperplasia, although in cis with a frameshift variant (e.g. Long_2016). This report not provide unequivocal conclusions about association of the variant with Congenital Adrenal Hyperplasia. At least one publication reports experimental evidence evaluating an impact on protein function, with COS-7 cells transfected with the variant showing 2% enzyme activity compared to ,cells transfected with wild-type (e.g. Long_2016). The following publication has been ascertained in the context of this evaluation (PMID: 26806323). ClinVar contains an entry for this variant (Variation ID: 553163). Based on the evidence outlined above, the variant was classified as likely pathogenic. -

This sequence change replaces aspartic acid, which is acidic and polar, with histidine, which is basic and polar, at codon 63 of the CYP11B1 protein (p.Asp63His). This variant is present in population databases (rs5282, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with CYP11B1-related conditions. ClinVar contains an entry for this variant (Variation ID: 553163). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt CYP11B1 protein function with a negative predictive value of 95%. 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. -
