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.

Benign, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpDec 04, 2017Variant summary: The APC c.2262T>G (p.Val754Val) variant involves the alteration of a non-conserved nucleotide causing a synonymous change and 4/5 splice prediction tools predict no significant impact on normal splicing. ESE finder predicts that this variant may create ESE binding sites at the locus. However, these predictions have yet to be confirmed by functional studies. This variant was found in 102/276142 control chromosomes (gnomAD), predominantly observed in the African subpopulation at a frequency of 0.003833 (92/24002). This frequency is about 54 times the estimated maximal expected allele frequency of a pathogenic APC variant (0.0000714), strongly suggesting this is likely a benign polymorphism found primarily in the populations of African origin. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as likely benign or benign. The variant of interest has not, to our knowledge, been reported in affected individuals via publications. Taken together, this variant is classified as benign. -
