MSH2 inversion of exons 1-7 was found in four probands previously suspected to have Lynch syndrome based on family history and tumor testing.

We used allelic dropout in long PCR to look for potential regions of rearrangement in the MSH2 gene. This method detected a potential rearrangement breakpoint in the same region of MSH2 where one breakpoint of a 10 Mb inversion was reported previously. We tested these ten patients for this inversion.

They showed that the centromeric and telomeric breakpoints of the paracentric inversion mapped within intron 7 of the MSH2 gene and to a contig 10 Mb 3-prime of MSH2… Pathogenicity of the paracentric inversion was demonstrated by conversion analysis. The patient's lymphocytes were employed to generate somatic cell hybrids to analyze the expression of the inverted MSH2 allele in an Msh2-deficient rodent cellular background. The inversion was shown to abolish MSH2 expression by both northern and western analysis. MSH2 inversion of exons 1-7 was found in four probands previously suspected to have Lynch syndrome based on family history and tumor testing. De novo (new) pathogenic variants in MSH2 are uncommon; and in this case, the inversion of exons 1-7 in MSH2 may be a pathogenic founder variant and as such, would likely be inherited from a parent. Biallelic pathogenic MSH2 variants, or any of the genes associated with Lynch syndrome, (i.e. 2004-02-11 Here, we report the identification and molecular characterization of the first paracentric inversion of the MSH2 locus known to cause HNPCC.

MSH2 Inversion Analysis. GTR Test ID Help Each Test is a specific, orderable test from a particular laboratory, and is assigned a unique GTR accession number. The format is GTR00000001.1, with a leading prefix 'GTR' followed by 8 digits, a period, then 1 or more digits representing the version.

Some physicians, genetic counselors, and other clinicians will consider Invitae’s omission of the MSH2 Boland inversion mutation to be minor—a hiccup in a field that advances through trial and error. But there will be some clinicians who distrust Invitae enough to refer their tests to other lab companies.

MSH2 variants classified by the InSiGHT consortium: criteria used for classification are available here.We encourage submission of relevant unpublished information to assist in the classification of variants via LOVD or this template which can be emailed to the curator.

We have also identified another inversion of exons 2 to 6 within the MSH2 gene in a different family with a history of Lynch syndrome, which will not be detected by the MLPA assay. It is currently unclear how common inversions within the MSH2 gene are and further testing of intronic regions within this gene would be required to gain a better understanding.
