Ambry Genetics RCV000115666 SCV000172770 pathogenic Hereditary cancer-predisposing syndrome 2021-09-09 criteria provided, single submitter clinical testing The c.1831dupA pathogenic mutation, located in coding exon 11 of the PMS2 gene, results from a duplication of A at nucleotide position 1831, causing a translational frameshift with a predicted alternate stop codon (p.I611Nfs*2). This mutation has been reported in multiple individuals with Lynch syndrome-associated cancers, many with tumors demonstrating microsatellite instability and/or loss of PMS2 by immunohistochemistry (Truninger K et al. Gastroenterology, 2005 May;128:1160-71; Senter L et al. Gastroenterology, 2008 Aug;135:419-28; Schofield L et al. Fam Cancer, 2012 Mar;11:1-6; Vaughn CP et al.

J Med Genet, 2020 07;57:487-499; Post CCB et al. J Natl Cancer Inst, 2021 Mar). In addition, this mutation has been identified as homozygous and in trans with additional PMS2 alterations in patients with constitutional mismatch repair deficiency (CMMRD) phenotypes (Lavoine N et al. J. Med. Genet. 2015 Nov;52:770-8; Alexander TB et al. Pediatr. Blood Cancer. 2016 Aug;63:1454-6; Mork ME et al. Fam. Cancer. 2016 Oct;15:587-91; Hildreth A et al. Case Rep.

This alteration has also been reported in 3/60,466 breast cancer cases and in 1/53,461 controls (Dorling et al. N Engl J Med. 2021 02;384:428-439). Of note, this alteration is also designated as 1828insA, c.1831_1832insA and 1831dup in published literature. In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation.
Invitae RCV000524450 SCV000218784 pathogenic Hereditary nonpolyposis colorectal neoplasms 2024-01-30 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Ile611Asnfs*2) in the PMS2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PMS2 are known to be pathogenic (PMID: 21376568, 24362816). This variant is present in population databases (rs63750250, gnomAD 0.005%). This premature translational stop signal has been observed in individual(s) with colorectal cancer and constitutional mismatch repair deficiency syndrome and Lynch syndrome or suspected Lynch syndrome and ovarian cancer (PMID: 15887099, 18602922, 20205264, 22577899, 23012243, 24728189, 25512458, 25980754, 26318770). This variant is also known as 1828insA, 1831insA, and 1831_1832insA. ClinVar contains an entry for this variant (Variation ID: 91317). For these reasons, this variant has been classified as Pathogenic.

Quest Diagnostics Nichols Institute San Juan Capistrano RCV000258972 SCV000601829 pathogenic not provided 2020-05-29 criteria provided, single submitter clinical testing The PMS2 c.1831dup (p.Ile611Asnfs*2) variant alters the translational reading frame of the PMS2 mRNA and causes the premature termination of PMS2 protein synthesis. This variant has been reported in the published literature in several individuals and families affected with colorectal cancer (PMIDs: 15887099 (2005), 25980754 (2015), 27978560 (2016), 30155321 (2018)). The frequency of this variant in the general population, 0.000046 (6/129170 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is consistent with pathogenicity. Based on the available information, this variant is classified as pathogenic.
Color Diagnostics, LLC DBA Color Health RCV000115666 SCV000686165 pathogenic Hereditary cancer-predisposing syndrome 2023-05-10 criteria provided, single submitter clinical testing This variant inserts 1 nucleotide in exon 11 of the PMS2 gene, creating a frameshift and premature translation stop signal. This variant is also known as 1828insA, 1831insA and c.1831_1832insA in the literature. This variant is expected to result in an absent or non-functional protein product. To our knowledge, functional studies have not been reported for this variant. This variant has been reported in individuals affected by/suspected of having Lynch syndrome (PMID: 18602922, 20205264, 22120844, 24728189, 25512458, 25856668, 26681312), in individuals affected by/suspected of having recessive constitutional DNA mismatch repair deficiency (CMMRD) syndrome (PMID: 26116798, 27017610, 27037742, 28562508, 32773772), and in a compound heterozygous individual affected with invasive adenocarcinoma (PMID: 30155321). This variant has been identified in 6/282838 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Loss of PMS2 function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000076830 SCV000697314 pathogenic Lynch syndrome 2016-08-29 criteria provided, single submitter clinical testing Variant summary: The PMS2 c.1831dupA (p.Ile611Asnfs) variant results in a premature termination codon, predicted to cause a truncated or absent PMS2 protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Mutation taster predicts a damaging outcome for this variant. This variant was found in 1/121354 control chromosomes at a frequency of 0.0000082, which does not exceed the estimated maximal expected allele frequency of a pathogenic PMS2 variant (0.0001136). It was reported in several cancer patients whose tumor had high MSI and lack of PMS2 staining based on IHC indicating pathogenicity. Additionally, truncations downstream of this position have been classified as pathogenic by our laboratory (e.g. p.Gln637fs) suggesting the clinical importance of the C-termial region located downstream of the variant. Moreover, multiple clinical diagnostic laboratories/reputable databases classified this variant as pathogenic. Taken together, this variant is classified as pathogenic.
Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine RCV000076830 SCV000711443 pathogenic Lynch syndrome 2019-04-19 criteria provided, single submitter clinical testing The p.Ile611AsnfsX2 variant in PMS2 has been reported in 12 individuals with colorectal cancer including 10 with Lynch Syndrome (Bodo 2015, ten Broeke 2015, Lavoine 2015, Goodenberger 2016, Susswein 2016), as well as in compound heterozygosity with another PMS2 variant in 2 individuals and 1 family member with constitutional MMR deficiency (Lavoine 2015, Bodo 2015, Susswein 2016). The p.Ile611AsnfsX2 variant has also been identified in 6/129170 of European chromosomes by gnomAD (http://gnomad.broadinstitute.org). In addition, it has been classified as Pathogenic on September 5, 2013 by the InSiGHT expert panel (ClinVar SCV000108317.2). This variant is predicted to cause a frameshift, which alters the protein’s amino acid sequence beginning at position 611 and leads to a premature termination codon 2 amino acids downstream. This alteration is then predicted to lead to a truncated or absent protein. Heterozygous loss of function of function of the PMS2 gene is an established disease mechanism in colorectal cancer. In summary, this variant meets criteria to be classified as pathogenic for autosomal dominant Lynch syndrome. ACMG/AMP criteria applied: PM2,PS4_Moderate, PM3_Supporting, PVS1.
