RCV004564406 | SCV000831197 | uncertain significance | Familial adenomatous polyposis 1 | 2024-07-24 | criteria provided, single submitter | clinical testing | This sequence change replaces threonine, which is neutral and polar, with arginine, which is basic and polar, at codon 1787 of the APC protein (p.Thr1787Arg). This variant is present in population databases (no rsID available, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with APC-related conditions. ClinVar contains an entry for this variant (Variation ID: 579136). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt APC protein function with a negative predictive value of 95%. 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. |
| Ambry Genetics | RCV002343543 | SCV002641606 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-06-26 | criteria provided, single submitter | clinical testing | The p.T1787R variant (also known as c.5360C>G), located in coding exon 15 of the APC gene, results from a C to G substitution at nucleotide position 5360. The threonine at codon 1787 is replaced by arginine, an amino acid with similar properties. This amino acid position is conserved. 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. |

RCV002343543 | SCV004363202 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-10-18 | criteria provided, single submitter | clinical testing | This missense variant replaces threonine with arginine at codon 1787 of the APC protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has been identified in 1/250382 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |
