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.5690A>C (p.His1897Pro) variant involves the alteration of a conserved nucleotide. It is not present in a known domain till date. 3/4 in silico tools predict a benign outcome (SNPs&GO not captured due to low reliability index). This variant was found in 10/120962 control chromosomes, predominantly observed in the African subpopulation at a frequency of 0.0008699 (9/10346). This frequency is about 12 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. Multiple clinical diagnostic laboratories have classified this variant as uncertain significance without evidence to independently evaluate. The variant of interest has been reported in one subject with suspected Lynch syndrome who also carried MSH2 c.1511-1G>A and BRIP1 p.His478Arg, supporting for the benign outcome (Yurgelun_2015). Taken together, this variant is currently classified as Likely Benign. -

Significance:Likely 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. -
