This sequence change replaces lysine with glutamic acid at codon 241 of the AIP protein (p.Lys241Glu). The lysine residue is highly conserved and there is a small physicochemical difference between lysine and glutamic acid. This variant is present in population databases (rs267606573, ExAC 0.008%). This variant has been observed in individual(s) with familial isolated pituitary adenoma (PMID: 17244780). ClinVar contains an entry for this variant (Variation ID: 41200). Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on AIP protein function (PMID: 20506337, 19366855). 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.
