Genes affected

AIP (HGNC:358): (aryl hydrocarbon receptor interacting protein) The protein encoded by this gene is a receptor for aryl hydrocarbons and a ligand-activated transcription factor. The encoded protein is found in the cytoplasm as part of a multiprotein complex, but upon binding of ligand is transported to the nucleus. This protein can regulate the expression of many xenobiotic metabolizing enzymes. Also, the encoded protein can bind specifically to and inhibit the activity of hepatitis B virus. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2014]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 307 of the AIP protein (p.Arg307Gln). This variant is present in population databases (no rsID available, gnomAD 0.03%), and has an allele count higher than expected for a pathogenic variant. This variant has not been reported in the literature in individuals affected with AIP-related conditions. ClinVar contains an entry for this variant (Variation ID: 837193). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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.
