The p.Glu1157Glu variant in APC is classified as benign because it does not alter an amino acid residue, is not located within the splice consensus site, and computational splice prediction tools do not predict an impact on splicing. It has been identified in 0.54% (135/25068) of Finnish chromosomes, including 1 homozygote, by gnomAD (http://gnomad.broadinstitute.org). ACMG/AMP Criteria applied: BA1, BP4, BP7. -
This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
Hereditary cancer-predisposing syndrome Benign:5
- -
- -
- -
- -
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. -

Familial adenomatous polyposis 1 Benign:2
This variant is considered benign. This variant is a silent/synonymous amino acid change and it is not expected to impact splicing. -
- -
Carcinoma of colon Benign:1
The p.Glu1157Glu variant is listed in dbSNP database (ID#: rs143927847) with an average heterozygosity of 0.011+/-0.074 in the human population, therefore increasing the likelihood that this variant is benign. This variant is not expected to have clinical significance because it does not alter an amino acid residue, is not located near a splice junction. In summary, based on above information this variant is classified as Benign. -
APC-Associated Polyposis Disorders Benign:1
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. -
