Invitae RCV003538498 SCV000768231 uncertain significance Familial adenomatous polyposis 1 2023-11-08 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 1832 of the APC protein (p.Asp1832Gly). This variant is present in population databases (rs537695710, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with APC-related conditions. ClinVar contains an entry for this variant (Variation ID: 537532). 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 not expected to disrupt APC protein function with a negative predictive value of 95%. RNA analysis performed to evaluate the impact of this missense change on mRNA splicing indicates it does not significantly alter splicing (Invitae). 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 RCV002343322 SCV002652713 uncertain significance Hereditary cancer-predisposing syndrome 2021-11-18 criteria provided, single submitter clinical testing The p.D1832G variant (also known as c.5495A>G), located in coding exon 15 of the APC gene, results from an A to G substitution at nucleotide position 5495. The aspartic acid at codon 1832 is replaced by glycine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
