Invitae | RCV000466263 | SCV000552679 | uncertain significance | Familial adenomatous polyposis 1 | 2023-11-24 | criteria provided, single submitter | clinical testing | This sequence change replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 2810 of the APC protein (p.Asn2810Lys). 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: 411493). 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%. 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. |

RCV001179768 | SCV001344510 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-08-28 | criteria provided, single submitter | clinical testing | This variant is located in the APC protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual affected with breast and/or ovarian cancer (PMID: 28528518). This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |
Ambry Genetics | RCV001179768 | SCV002675891 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-09-07 | criteria provided, single submitter | clinical testing | The p.N2810K variant (also known as c.8430T>A), located in coding exon 15 of the APC gene, results from a T to A substitution at nucleotide position 8430. The asparagine at codon 2810 is replaced by lysine, an amino acid with similar properties. This alteration has been reported in a cohort of 85 Colombian breast and/or ovarian cancer patients and was called a variant of unknown significance (Cock-Rada AM et al. Fam. Cancer, 2018 01;17:23-30). 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. |
