• Clinical Significance: Likely benign criteria provided, single submitter B:1
• Conservation: PhyloP100: -0.189

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.
