ClinVar
Submissions by phenotype
Familial adenomatous polyposis 1 Benign:3
This variant is considered benign. This variant is a silent/synonymous amino acid change and it is not expected to impact splicing. -
- -
The APC p.Ala571Ala variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. In addition, in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. The variant was not identified in the literature, nor was it identified in dbSNP, the NHLBI Exome Sequencing Project (Exome Variant Server), HGMD, UMD, the “InSiGHT Colon Cancer Database”, or the COSMIC database. This variant was identified by our laboratory in a patient with a co-occurring pathogenic MUTYH mutation in homozygous state, increasing the likelihood that the APC p.Ala571Ala variant does not have clinical significance. In summary, based on the above information, the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as predicted benign. -
not specified Benign:2
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:2
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. -
