Ambry Genetics | RCV001017728 | SCV001178854 | uncertain significance | Hereditary cancer-predisposing syndrome | 2018-08-30 | criteria provided, single submitter | clinical testing | The p.T99S variant (also known as c.296C>G), located in coding exon 4 of the PMS2 gene, results from a C to G substitution at nucleotide position 296. The threonine at codon 99 is replaced by serine, an amino acid with similar properties. This amino acid position is not well 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. |

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 PMS2 protein function. ClinVar contains an entry for this variant (Variation ID: 822396). This variant has not been reported in the literature in individuals affected with PMS2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces threonine, which is neutral and polar, with serine, which is neutral and polar, at codon 99 of the PMS2 protein (p.Thr99Ser). |
