RCV001067459 | SCV001232524 | uncertain significance | not provided | 2024-01-13 | 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 39 of the AIP protein (p.Arg39Trp). This variant is present in population databases (rs781366620, gnomAD 0.004%). 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: 861039). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae 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. |
| Ambry Genetics | RCV002374981 | SCV002626127 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-11-20 | criteria provided, single submitter | clinical testing | The p.R39W variant (also known as c.115C>T), located in coding exon 2 of the AIP gene, results from a C to T substitution at nucleotide position 115. The arginine at codon 39 is replaced by tryptophan, an amino acid with dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
