RCV001861893 | SCV002278914 | uncertain significance | RASopathy | 2023-10-23 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 490 of the PTPN11 protein (p.Val490Ile). This variant is present in population databases (rs781083623, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with PTPN11-related conditions. ClinVar contains an entry for this variant (Variation ID: 561751). 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 PTPN11 protein function. 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 | RCV002388191 | SCV002702176 | uncertain significance | Cardiovascular phenotype | 2019-04-08 | criteria provided, single submitter | clinical testing | The p.V490I variant (also known as c.1468G>A), located in coding exon 13 of the PTPN11 gene, results from a G to A substitution at nucleotide position 1468. The valine at codon 490 is replaced by isoleucine, 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. |
