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.

The APC p.Glu565Glu variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. The variant is listed in UMD (3X) as a neutral variant (co-occurring with a pathogenic APC variant in one sample), in the ClinVar database (classified as benign by Ambry Genetics), and in the Invitae database (classified as â€šÃ„Ãºvariant of unknown significanceâ€šÃ„Ã¹ by Emory Genetics). Three of five in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predict the potential creation of a 5â€šÃ„Ã´ splice site; however, this information is not predictive enough to assume pathogenicity. The variant was identified in the literature in 10 of 1695 familial adenomatous polyposis cases (allelic frequency: 0.003); the authors suggest the variant is likely benign due to a co-occurring pathogenic APC variant identified in at least one of these individuals (Kerr 2013). In addition, the variant was identified in several populations at polymorphic allelic frequencies: 1000 Genomes Project (frequency: 0.014), Exome Variant Server ESP project (African American cohort frequency: 0.036, and the ExAC browser (African cohort frequency: 0.038). In summary, based on the above information, this variant meets our laboratory's criteria to be classified as benign. -

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
