| Invitae | RCV003535858 | SCV000932408 | uncertain significance | Familial adenomatous polyposis 1 | 2022-11-14 | criteria provided, single submitter | clinical testing | This variant is present in population databases (no rsID available, gnomAD 0.0009%). 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: 640116). This variant has not been reported in the literature in individuals affected with APC-related conditions. This sequence change replaces serine, which is neutral and polar, with threonine, which is neutral and polar, at codon 1238 of the APC protein (p.Ser1238Thr). |
| Ambry Genetics | RCV002352315 | SCV002624955 | uncertain significance | Hereditary cancer-predisposing syndrome | 2021-06-04 | criteria provided, single submitter | clinical testing | The p.S1238T variant (also known as c.3713G>C), located in coding exon 15 of the APC gene, results from a G to C substitution at nucleotide position 3713. The serine at codon 1238 is replaced by threonine, 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. |
