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.

Variant summary: The APC c.4212C>A (p.Ser1404Ser) variant causes a synonymous change involving a non-conserved nucleotide, 4/5 splice prediction tools predict no significant impact on normal splicing and ESE finder predicts alterations to ESE binding, although these predictions have yet to be functionally assessed. The variant of interest has been observed in the large, broad control population, ExAC, with an allele frequency of 11/121300 (1/11025), which exceeds the estimated maximal expected allele frequency for a pathogenic APC variant of 1/14005, therefore, suggesting this variant is likely a benign polymorphism. In addition, multiple clinical diagnostic laboratories classified this variant as likely benign. The variant of interest has not, to our knowledge, been reported in affected individuals via publications. Therefore, the variant of interest has been classified as Benign. -

Review Status: criteria provided, single submitter
Collection Method: clinical testing

This 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. -
