RCV002530045 | SCV000768134 | uncertain significance | Familial adenomatous polyposis 1 | 2022-05-26 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (gnomAD no frequency). This sequence change replaces proline, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 437 of the APC protein (p.Pro437Ala). This variant has not been reported in the literature in individuals affected with APC-related conditions. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 537475). |
Ambry Genetics | RCV002386082 | SCV002694294 | uncertain significance | Hereditary cancer-predisposing syndrome | 2017-11-06 | criteria provided, single submitter | clinical testing | The p.P437A variant (also known as c.1309C>G), located in coding exon 9 of the APC gene, results from a C to G substitution at nucleotide position 1309. The proline at codon 437 is replaced by alanine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, in silico predictors for this gene do not accurately predict pathogenicity. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
