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]
MIR6752 (HGNC:50020): (microRNA 6752) microRNAs (miRNAs) are short (20-24 nt) non-coding RNAs that are involved in post-transcriptional regulation of gene expression in multicellular organisms by affecting both the stability and translation of mRNAs. miRNAs are transcribed by RNA polymerase II as part of capped and polyadenylated primary transcripts (pri-miRNAs) that can be either protein-coding or non-coding. The primary transcript is cleaved by the Drosha ribonuclease III enzyme to produce an approximately 70-nt stem-loop precursor miRNA (pre-miRNA), which is further cleaved by the cytoplasmic Dicer ribonuclease to generate the mature miRNA and antisense miRNA star (miRNA*) products. The mature miRNA is incorporated into a RNA-induced silencing complex (RISC), which recognizes target mRNAs through imperfect base pairing with the miRNA and most commonly results in translational inhibition or destabilization of the target mRNA. The RefSeq represents the predicted microRNA stem-loop. [provided by RefSeq, Sep 2009]

This sequence change replaces lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 241 of the AIP protein (p.Lys241Glu). This variant is present in population databases (rs267606573, gnomAD 0.008%). This missense change has been observed in individual(s) with familial isolated pituitary adenoma (PMID: 17244780). ClinVar contains an entry for this variant (Variation ID: 41200). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt AIP protein function with a negative predictive value of 80%. Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on AIP function (PMID: 19366855, 20506337). 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. -

The p.K241E variant (also known as c.721A>G), located in coding exon 5 of the AIP gene, results from an A to G substitution at nucleotide position 721. The lysine at codon 241 is replaced by glutamic acid, an amino acid with similar properties. This alteration has been observed in patients with pituitary adenomas (Daly AF et al. J Clin Endocrinol Metab, 2007 May;92:1891-6; Jaffrain-Rea ML et al. Endocr Relat Cancer, 2009 Sep;16:1029-43). Protein functional studies have shown this alteration to be potentially deleterious to PDE4A5 interactions, but to not impair the AIP-RET interaction (Bolger GB et al. Endocr Relat Cancer, 2016 05;23:419-31; Igreja S et al. Hum Mutat, 2010 Aug;31:950-60; Vargiolu M et al. J Clin Endocrinol Metab, 2009 Jul;94:2571-8). This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is conflicting at this time, the clinical significance of this alteration remains unclear. -
