Invitae RCV001040387 SCV001203958 uncertain significance Hereditary nonpolyposis colorectal neoplasms 2021-11-13 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). 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 PMS2 protein function. ClinVar contains an entry for this variant (Variation ID: 838773). This variant has not been reported in the literature in individuals affected with PMS2-related conditions. This sequence change replaces serine, which is neutral and polar, with threonine, which is neutral and polar, at codon 34 of the PMS2 protein (p.Ser34Thr).
Ambry Genetics RCV002363573 SCV002663678 uncertain significance Hereditary cancer-predisposing syndrome 2022-04-06 criteria provided, single submitter clinical testing The p.S34T variant (also known as c.101G>C), located in coding exon 2 of the PMS2 gene, results from a G to C substitution at nucleotide position 101. The serine at codon 34 is replaced by threonine, 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.
