RCV000656943 | SCV000149619 | uncertain significance | not provided | 2023-07-27 | criteria provided, single submitter | clinical testing | In silico analysis supports that this missense variant does not alter protein structure/function; Observed in individuals with colorectal or breast cancer (Hampel et al., 2018; Jiang et al., 2019; Hu et al., 2022); This variant is associated with the following publications: (PMID: 30521064, 29596542, 32980694, 11574484, 35449176) |
Ambry Genetics | RCV000115710 | SCV000185566 | likely benign | Hereditary cancer-predisposing syndrome | 2022-11-23 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. |
Invitae | RCV000469956 | SCV000552057 | uncertain significance | Hereditary nonpolyposis colorectal neoplasms | 2024-01-03 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 306 of the PMS2 protein (p.Val306Met). This variant is present in population databases (rs587780063, gnomAD 0.006%). This missense change has been observed in individual(s) with clinical features of Lynch syndrome (PMID: 30521064, 31391288, 34326862). ClinVar contains an entry for this variant (Variation ID: 127801). 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 with a positive predictive value of 80%. 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. |
Quest Diagnostics Nichols Institute San Juan Capistrano | RCV000656943 | SCV000601864 | uncertain significance | not provided | 2023-01-11 | criteria provided, single submitter | clinical testing | The frequency of this variant in the general population, 0.000021 (6/282508 chromosomes, http://gnomad.broadinstitute.org), is uninformative in assessment of its pathogenicity. In the published literature, the variant has been reported in individuals with colorectal cancer (PMIDs: 30521064 (2019), 29596542 (2018)) and an unspecified Lynch syndrome-associated cancer (PMID: 31391288 (2020)). The variant has also been observed in control individuals in pancreatic and breast cancer screening studies (PMID 32980694 (2020), 33471991 (2021) and LOVD (http://databases.lovd.nl/shared/genes/PMS2)). Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is damaging. Based on the available information, we are unable to determine the clinical significance of this variant. |

RCV000115710 | SCV000686257 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-03-17 | criteria provided, single submitter | clinical testing | This missense variant replaces valine with methionine at codon 306 of the PMS2 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual affected with colorectal cancer (PMID: 30521064) and an individual affected with an unspecified cancer (PMID: 31391288). This variant has been identified in 6/282508 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |
