Submissions by phenotype
not specified Uncertain:1Benign:3
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:4
- -
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. -
- -
- -
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. -
not provided Uncertain:1
The APC c.8199A>G (p.Gln2733=) synonymous variant has not been reported in individuals with APC-related conditions in the published literature. The frequency of this variant in the general population, 0.000046 (6/129092 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using software algorithms for the prediction of the effect of nucleotide changes on splicing yielded predictions that this variant does not affect APC mRNA splicing. Based on the available information, we are unable to determine the clinical significance of this variant. -
