| Ambry Genetics | RCV001016196 | SCV001177120 | uncertain significance | Hereditary cancer-predisposing syndrome | 2019-03-12 | criteria provided, single submitter | clinical testing | The p.T882S variant (also known as c.2644A>T), located in coding exon 15 of the APC gene, results from an A to T substitution at nucleotide position 2644. The threonine at codon 882 is replaced by serine, an amino acid with similar properties. This amino acid position is not 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. |
| Invitae | RCV003633554 | SCV004560971 | uncertain significance | Familial adenomatous polyposis 1 | 2023-03-04 | criteria provided, single submitter | clinical testing | 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. 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. ClinVar contains an entry for this variant (Variation ID: 821623). This variant has not been reported in the literature in individuals affected with APC-related conditions. This variant is present in population databases (rs761780458, gnomAD 0.003%). This sequence change replaces threonine, which is neutral and polar, with serine, which is neutral and polar, at codon 882 of the APC protein (p.Thr882Ser). |
