| Invitae | RCV003653354 | SCV000943973 | uncertain significance | Familial adenomatous polyposis 1 | 2022-11-23 | 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. 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. ClinVar contains an entry for this variant (Variation ID: 649201). This variant has not been reported in the literature in individuals affected with APC-related conditions. This variant is present in population databases (rs745815339, gnomAD 0.0009%). This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 2437 of the APC protein (p.Leu2437Phe). |
| Ambry Genetics | RCV001026261 | SCV001188606 | uncertain significance | Hereditary cancer-predisposing syndrome | 2019-06-03 | criteria provided, single submitter | clinical testing | The p.L2437F variant (also known as c.7311A>C), located in coding exon 15 of the APC gene, results from an A to C substitution at nucleotide position 7311. The leucine at codon 2437 is replaced by phenylalanine, an amino acid with highly similar properties. This amino acid position is highly conserved in available 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. |
