RCV001187485 | SCV001354303 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-12-04 | criteria provided, single submitter | clinical testing | This missense variant replaces glutamic acid with glycine at codon 1461 of the APC protein. Computational prediction tools and conservation analyses are inconclusive regarding the impact of this variant on the protein function. Splice site prediction tools suggest that this variant may not impact RNA splicing. To our knowledge, functional assays have not been performed for this variant nor has this variant been reported in individuals affected with hereditary cancer in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). 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 | RCV001187485 | SCV005032808 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-01-12 | criteria provided, single submitter | clinical testing | The p.E1461G variant (also known as c.4382A>G), located in coding exon 15 of the APC gene, results from an A to G substitution at nucleotide position 4382. The glutamic acid at codon 1461 is replaced by glycine, an amino acid with similar properties. This amino acid position is conserved. In addition, in silico predictors for this gene do not accurately predict pathogenicity. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |

RCV005093952 | SCV005782658 | uncertain significance | Familial adenomatous polyposis 1 | 2024-10-15 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 1461 of the APC protein (p.Glu1461Gly). 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: 925509). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) 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. |
