Variant summary
Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4_ModerateBS2
The NM_003977.4(AIP):c.70G>C(p.Glu24Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000112 in 1,614,096 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E24D) has been classified as Likely benign.

Hereditary cancer-predisposing syndrome Uncertain:2
The c.70G>C (p.E24Q) alteration is located in exon 1 (coding exon 1) of the AIP gene. This alteration results from a G to C substitution at nucleotide position 70, causing the glutamic acid (E) at amino acid position 24 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
Somatotroph adenoma Uncertain:1
not provided Uncertain:1
This sequence change replaces glutamic acid, which is acidic and polar, with glutamine, which is neutral and polar, at codon 24 of the AIP protein (p.Glu24Gln). This variant is present in population databases (no rsID available, gnomAD 0.003%). 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: 826838). 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%. 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.
