Ambry Genetics RCV001022558 SCV001184310 uncertain significance Hereditary cancer-predisposing syndrome 2019-09-12 criteria provided, single submitter clinical testing The p.S1495N variant (also known as c.4484G>A), located in coding exon 15 of the APC gene, results from a G to A substitution at nucleotide position 4484. The serine at codon 1495 is replaced by asparagine, an amino acid with highly similar properties. This amino acid position is highly 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.
GeneDx RCV002466604 SCV002762006 uncertain significance not provided 2022-06-07 criteria provided, single submitter clinical testing Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge; This variant is associated with the following publications: (PMID: 18199528)
Invitae RCV003537412 SCV004336431 uncertain significance Familial adenomatous polyposis 1 2023-10-20 criteria provided, single submitter clinical testing This sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 1495 of the APC protein (p.Ser1495Asn). This variant is not present in population databases (gnomAD no frequency). 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: 824929). 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. 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.
