ClinVar
Submissions by phenotype
Familial adenomatous polyposis 1 Uncertain:1Benign:2
- -
This variant is considered likely benign. This variant has been observed at a population frequency that is significantly greater than expected given the associated disease prevalence and penetrance. -
- -
not provided Benign:2
- -
- -
Hereditary cancer-predisposing syndrome Benign:2
- -
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. -
not specified Benign:1
Variant summary: APC c.7109G>T (p.Gly2370Val) results in a non-conservative amino acid change located in the Adenomatous polyposis coli protein basic domain of the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 2.7e-05 in 1613238 control chromosomes, predominantly at a frequency of 0.00055 within the African or African-American subpopulation in the gnomAD database (v4). The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 8 fold of the estimated maximal expected allele frequency for a pathogenic variant in APC causing Familial Adenomatous Polyposis phenotype (7.1e-05). c.7109G>T has been reported in the literature in one individual affected with breast cancer (Tung_2015). These report(s) do not provide unequivocal conclusions about association of the variant with Familial Adenomatous Polyposis. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 25186627). ClinVar contains an entry for this variant (Variation ID: 236640). Based on the evidence outlined above, the variant was classified as likely benign. -
APC-related disorder Benign:1
This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). -
