Invitae RCV001043319 SCV001207052 uncertain significance Hereditary nonpolyposis colorectal neoplasms 2023-10-12 criteria provided, single submitter clinical testing This sequence change replaces asparagine, which is neutral and polar, with tyrosine, which is neutral and polar, at codon 324 of the PMS2 protein (p.Asn324Tyr). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with PMS2-related conditions. ClinVar contains an entry for this variant (Variation ID: 631072). 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 expected to disrupt PMS2 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.
