Genes affected

APC (HGNC:583): (APC regulator of WNT signaling pathway) This gene encodes a tumor suppressor protein that acts as an antagonist of the Wnt signaling pathway. It is also involved in other processes including cell migration and adhesion, transcriptional activation, and apoptosis. Defects in this gene cause familial adenomatous polyposis (FAP), an autosomal dominant pre-malignant disease that usually progresses to malignancy. Mutations in the APC gene have been found to occur in most colorectal cancers, where disease-associated mutations tend to be clustered in a small region designated the mutation cluster region (MCR) and result in a truncated protein product.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces aspartic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 610 of the APC protein (p.Asp610Gly). This variant is present in population databases (rs756090401, gnomAD 0.005%). This missense change has been observed in individual(s) with APC-related conditions (PMID: 31422818). ClinVar contains an entry for this variant (Variation ID: 230672). 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.

The APC c.1829A>G (p.Asp610Gly) missense change has a maximum subpopulation frequency of 0.0050% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). The in silico tool REVEL is inconclusive about a pathogenic or benign effect of this variant on protein function, and to our knowledge functional studies have not been performed. To our knowledge, this variant has not been reported in individuals with APC-related familial adenomatous polyposis. In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This missense variant replaces aspartic acid with glycine at codon 610 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 been reported in individual affected with colorectal cancer or more than one colon polyps (PMID: 31422818). This variant has been identified in 3/282718 chromosomes 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.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.D610G variant (also known as c.1829A>G), located in coding exon 14 of the APC gene, results from an A to G substitution at nucleotide position 1829. The aspartic acid at codon 610 is replaced by glycine, an amino acid with similar properties. This alteration was detected in a study of 1165 individuals with a history of colorectal cancer or colon polyps as well as 590 controls (Gordon AS et al. Am J Hum Genet, 2019 Sep;105:526-533). This amino acid position is well conserved in available vertebrate species. In addition, in silico predictors for this gene do not accurately predict pathogenicity. Based on the available evidence, the clinical significance of this alteration remains unclear.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.Asp610Gly variant in APC has not been previously reported in individuals w ith APC-associated polyposis. This variant has been identified in 1/8642 of East Asian chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadi nstitute.org; dbSNP rs756090401). Computational prediction tools and conservatio n analysis do not provide strong support for or against an impact to the protein . In summary, the clinical significance of the p.Asp610Gly variant is uncertain.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The APC c.1829A>G (p.Asp610Gly) variant has been reported in the published literature in at least one individual with colorectal cancer or polyps (PMID: 31422818 (2019)) and in an individual with non-small cell lung cancer who also developed brain metastasis (PMID: 37591896 (2023)). The frequency of this variant in the general population, 0.000011 (3/282718 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is benign. Based on the available information, we are unable to determine the clinical significance of this variant.
