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]

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 4886). This premature translational stop signal has been observed in individual(s) with pituitary adenoma (PMID: 16728643). This variant is present in population databases (rs104894194, gnomAD 0.03%). This sequence change creates a premature translational stop signal (p.Gln14*) in the AIP gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in AIP are known to be pathogenic (PMID: 23321498, 26186299). -

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.Q14* pathogenic mutation (also known as c.40C>T), located in coding exon 1 of the AIP gene, results from a C to T substitution at nucleotide position 40. This changes the amino acid from a glutamine to a stop codon within coding exon 1. This mutation has been reported in multiple individuals, predominantly of Finnish descent, with familial isolated pituitary adenomas (Vierimaa O et al. Science 2006 May;312(5777):1228-30; Georgitsi M et al. Proc. Natl. Acad. Sci. U.S.A. 2007 Mar;104(10):4101-5; Beckers A et al. Endocr. Rev. 2013 Apr;34(2):239-77). This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. -
