Genes affected

CYP19A1 (HGNC:2594): (cytochrome P450 family 19 subfamily A 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 endoplasmic reticulum and catalyzes the last steps of estrogen biosynthesis. Mutations in this gene can result in either increased or decreased aromatase activity; the associated phenotypes suggest that estrogen functions both as a sex steroid hormone and in growth or differentiation. Alternative promoter use and alternative splicing results in multiple transcript variants that have different tissue specificities. [provided by RefSeq, Dec 2016]

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 435 of the CYP19A1 protein (p.Arg435Cys). This variant is present in population databases (rs121434534, gnomAD 0.006%). This missense change has been observed in individuals with aromatase deficiency (PMID: 8265607, 17164303, 23329769, 27256151). ClinVar contains an entry for this variant (Variation ID: 17815). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt CYP19A1 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects CYP19A1 function (PMID: 8265607, 17164303). For these reasons, this variant has been classified as Pathogenic. -
