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.3468_3470delAGA (p.Glu1157del) variant causes deletion of a Glutamic acid in a run of 4 repetitive Glutamic acids. This variant was found in 148/121852 control chromosomes (1 homozygote), predominantly observed in the African subpopulation at a frequency of 0.0130777 (133/10170). This frequency is about 183 times the estimated maximal expected allele frequency of a pathogenic APC variant (0.0000714), suggesting this is likely a benign polymorphism found primarily in the populations of African origin. The variant of interest has been reported in patients with familial adenomatous polyposis including co-occurrences with other potentially pathogenic variants (Grandval_2014), supporting for the benign outcome. In addition, multiple clinical diagnostic laboratories/reputable databases have classified this variant as likely benign/benign. Taken together, this variant is 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. -
