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.

Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsJan 22, 2015This alteration is classified as likely 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. -

Likely benign, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpMay 23, 2019Variant summary: APC c.4533C>T alters a non-conserved nucleotide resulting in a synonymous change. 5/5 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 4.8e-05 in 250356 control chromosomes, predominantly within the Non-Finnish European subpopulation at a frequency of 7.1e-05 in the gnomAD database. The observed variant frequency in the Non-Finnish European subpopulation is approximately the same as the estimated maximal expected allele frequency for a pathogenic variant in APC causing Familial Adenomatous Polyposis (FAP) phenotype (7.1e-05), suggesting that the variant is benign. In addition, the variant occurs in the North-western European subpopulation with an even higher frequency (i.e. 0.00012) further supporting a benign role. To our knowledge, no occurrence of c.4533C>T in individuals affected with Familial Adenomatous Polyposis and no experimental evidence demonstrating its impact on protein function have been reported. Five other clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation, and all of them classified the variant as likely benign. Based on the evidence outlined above, the variant was classified as likely benign. -
