Description

In silico analysis indicates that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 26483394, 31422574, 22229248, 27449771, 28135145, 29101607, 29785153, 25186627, 31159747, 30613976, 34271781, 33120919, 26321251, 35372080, 35402282, 30113427, 35089076, 33471991, 37534630, 35263119, 34326862, 11292842)

Description

The frequency of this variant in the general population, 0.00035 (29/83638 chromosomes, http://gnomad.broadinstitute.org), is uninformative in assessment of its pathogenicity. In the published literature, the variant has been reported in affected individuals with pancreatic cancer (PMIDs: 26483394 (2015) and 27449771 (2016)), breast cancer (PMIDs: 25186627 (2015), 29785153 (2018), 31159747 (2019), 31422574 (2019), 33120919 (2020), 35402282 (2022)), and colorectal cancer (PMIDs: 28135145 (2017), 34271781 (2021)). It has been reported in individuals with breast cancer as well as in unaffected controls in a breast cancer association study (PMID: 33471991 (2021), see also 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 benign. Based on the available information, we are unable to determine the clinical significance of this variant.

Description

The PMS2 p.Thr671Met variant was identified in 3 of 260 proband chromosomes (frequency: 0.01) from individuals or families with breast cancer of Romanian ethnicity (Goidescu 2017). The variant was also identified in dbSNP (ID: rs587780046) as with uncertain significance allele; and in ClinVar and Clinvitae databases as benign by Ambry Genetics and uncertain significance by Invitae, Praxis fuer Humangenetik Tuebingen, Quest Diagnostics - Nichols Institute San Juan Capistrano, Fulgent Genetics, GeneDx and Pathway Genomics. The variant was not identified in GeneInsight-COGR, Cosmic, MutDB, Insight Colon Cancer Gene Variant Database, Zhejiang Colon Cancer Database, Mismatch Repair Genes Variant Database, Insight Hereditary Tumors Database, databases. The variant was identified in control databases in 34 of 195042 chromosomes at a frequency of 0.0002 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). Breakdown of the observations by population include other in 3 of 5030 chromosomes (freq: 0.0006), European Non-Finnish in 27 of 81252 chromosomes (freq: 0.0003), East Asian in 2 of 13498 chromosomes (freq: 0.0001), and South Asian in 2 of 23600 chromosomes (freq: 0.0001), while the variant was not observed in the African, Latino, Ashkenazi Jewish, European Finnish, populations. The p.Thr671 residue is not conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance.
