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:Benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant Summary: The c.7490C>T variant involves the alteration of a conserved nucleotide and 3/4 in silico tools predict a neutral outcome. The variant was observed in the large and broad cohorts of the ExAC project at an allele frequency of 0.033%, predominantly observed in the European (Non-Finnish) subpopulation at a frequency of 0.055%. This frequency exceeds the maximal expected allele frequency for a pathogenic variant in APC (0.006%), suggesting this is a benign polymorphism found primarily in population(s) of European origin. The variant was reported in a family affected by multiple colorectal adenomas and carcinoma, however was absent in two affected members and was present in 3 unaffected members, showing lack of segregation of the variant with disease (Al-Tassan_2002). While one reputable clinical lab has classified the variant as likely benign, others have classified it as a VUS. Considering the relatively high frequency of this variant in the general population as well as the lack of segregation seen in an affected family, this variant has been classified as Benign. -

Significance:Benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

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. -

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
