Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_000038.6(APC):c.8461G>A(p.Asp2821Asn) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D2821G) has been classified as Likely benign.

Intrahepatic cholangiocarcinoma Uncertain:1
Uncertain significance, no assertion criteria provided | clinical testing | 3DMed Clinical Laboratory Inc | Nov 22, 2017 | - - |
Classic or attenuated familial adenomatous polyposis Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | All of Us Research Program, National Institutes of Health | May 16, 2023 | This missense variant replaces aspartic acid with asparagine at codon 2821 of 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 not been reported in individuals affected with APC-related disorders in the literature. 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. - |
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 30, 2021 | The p.D2821N variant (also known as c.8461G>A), located in coding exon 15 of the APC gene, results from a G to A substitution at nucleotide position 8461. The aspartic acid at codon 2821 is replaced by asparagine, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species. 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. - |
