| Ambry Genetics | RCV000564964 | SCV000672446 | likely benign | Hereditary cancer-predisposing syndrome | 2023-03-22 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. |

RCV001040402 | SCV001203974 | uncertain significance | not provided | 2024-12-02 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 323 of the AIP protein (p.Arg323Trp). This variant is present in population databases (rs188965257, gnomAD 0.05%), and has an allele count higher than expected for a pathogenic variant. This missense change has been observed in individual(s) with nonfunctioning pituitary adenoma (PMID: 24050928). ClinVar contains an entry for this variant (Variation ID: 485063). 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 expected to disrupt AIP protein function with a positive 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. |

RCV001526825 | SCV001737489 | uncertain significance | Familial isolated pituitary adenoma | 2021-05-13 | criteria provided, single submitter | clinical testing | The AIP c.967C>T (p.Arg323Trp) missense change has a maximum subpopulation frequency of 0.057% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/variant/11-67258438-C-T?dataset=gnomad_r2_1). In silico tools are not in agreement about the effect of this variant on protein function, but these predictions have not been confirmed by functional studies. This variant has been reported in a male with a nonfunctioning pituitary adenoma whose tumor showed loss of heterozygosity (PS4_supporting; PMID: 24050928). In summary, this variant meets criteria to be classified as of uncertain significance based on the ACMG/AMP criteria: PS4_supporting. |
