Ambry Genetics | RCV000584686 | SCV002652180 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-09-27 | criteria provided, single submitter | clinical testing | The p.T1932A variant (also known as c.5794A>G), located in coding exon 15 of the APC gene, results from an A to G substitution at nucleotide position 5794. The threonine at codon 1932 is replaced by alanine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species; however, alanine is the reference amino acid in other vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
Invitae | RCV003744594 | SCV003217262 | uncertain significance | Familial adenomatous polyposis 1 | 2022-07-06 | criteria provided, single submitter | clinical testing | 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 missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The alanine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 490321). This variant has not been reported in the literature in individuals affected with APC-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces threonine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 1932 of the APC protein (p.Thr1932Ala). |
