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.

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. -

The p.Leu2401Leu variant is not expected to have clinical significance because it does not alter an amino acid residue, is not located near a splice junction, and is listed in the dbSNP database as coming from a "clinical source" (ID#: rs2229994) with an average heterozygosity of 0.022+/-0.103, therefore increasing the likelihood of this variant to be benign. It has been identified in our laboratory in one among the 973 individuals who have undergone APC testing. Additionally, it has been identified twice in the literature, in 2/258 (0.007% frequency) proband chromosomes and 1/1052 (0.001 frequency) control chromosomes where it was classified as a polymorhism (Hadjisavvas_2006_16650078, Zhou_2004_15122587). In summary, based on the above information, the p.Leu2401Leu variant is classified as predicted benign. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
