Genes affected

AHR (HGNC:348): (aryl hydrocarbon receptor) The protein encoded by this gene is a ligand-activated helix-loop-helix transcription factor involved in the regulation of biological responses to planar aromatic hydrocarbons. This receptor has been shown to regulate xenobiotic-metabolizing enzymes such as cytochrome P450. Before ligand binding, the encoded protein is sequestered in the cytoplasm; upon ligand binding, this protein moves to the nucleus and stimulates transcription of target genes.

This sequence change replaces proline, which is neutral and non-polar, with glutamine, which is neutral and polar, at codon 25 of the AHR protein (p.Pro25Gln). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with AHR-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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. -
