KW - Lynch syndrome. KW - MSH2 inversion A germline inversion of exons 1-7 in MSH2 has been reported in fourteen individuals from eleven unrelated families clinically presenting with Lynch syndrome associated phenotypes including colorectal, endometrial, gastric, and ovarian cancer (Wagner et al. 2002. PubMed ID: 12203789; Rhees et al. 2013. The microsatellite DNA instability that is associated with alteration in the MSH2 gene in hereditary nonpolyposis colon cancer and several forms of sporadic cancer is thought to arise from defective repair of DNA replication errors that create insertion-deletion loop-type (IDL) mismatched nucleotides.

Six of 10 patients had the inversion, indicating the importance of including testing for this inversion in patients suspected of having MSH2-type Lynch syndrome in our population. Additionally, this method could be further developed to look for inversions in other genes where current methods of testing fail to find a causative mutation. Rhees J et al. Inversion of exons 1-7 of the MSH2 gene is a frequent cause of unexplained Lynch syndrome in one local population. Fam Cancer. 2014 Jun;13(2):219-25. (PMID: 24114314) Senter L et al.

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. This strategy amplifies only the wild type allele of MSH2, and therefore patients who are heterozygous for the internal SNP are homozygous in the PCR product if they also carry the inversion in MSH2. Only carriers of the inversion displayed allelic drop out in the long PCR, and no inversion carriers had amplification of both alleles (Fig. 2).

Gastroenterology 2014, 146:643-646.e8. 24333619 Approximately one-third of individuals diagnosed with colorectal cancer have a family history of cancer, suggesting that CRCs may result from a heritable component. Despite the availability of current gene-identification techniques, only 5% of all CRCs emerge from well-identifiable inherited causes for predisposition, including polyposis and nonpolyposis syndromes.

Only carriers of the inversion displayed allelic drop out in the long PCR, and no inversion carriers had amplification of both alleles ( Fig. 2 ). MSH2: Inversion of MSH2 exons 1-7 ("Boland" inversion) is assessed for Lynch Syndrome, Colorectal, Endometrial, and Prostate Cancer Panel testing (for both Focus and Comprehensive Panels) as well as Comprehensive Gastric Cancer Panel testing. Genomic deletions of the MSH2 gene are a frequent cause of hereditary nonpolyposis colorectal cancer (HNPCC), a common hereditary predisposition to the development of tumors in several organs includi An inversion PCR on germline DNA identified an ~18kb unbalanced, paracentric inversion within MSH2, with breakpoints in a long terminal repeat in intron 1 and an Alu repeat in intron 6.

In the literature, it is also known as the 10-Mb paracentric inversion of the MSH2 gene. Identifying the genetic cause of a condition can allow clinicians to accurately manage a patient. Find the right test. MSH2 inversions are not, however, as readily detected by commercial platforms and should be considered in apparently nonmutated cases with a strong clinical suspicion and MSH2/MSH6 loss of expression. Inversion of exons 1-7 of the MSH2 gene is a frequent cause of unexplained Lynch syndrome in one local population.

DNA mismatch repair protein Msh2 also known as MutS homolog 2 or MSH2 is a protein that in humans is encoded by the MSH2 gene, which is located on chromosome 2.MSH2 is a tumor suppressor gene and more specifically a caretaker gene that codes for a DNA mismatch repair (MMR) protein, MSH2, which forms a heterodimer with MSH6 to make the human MutSα mismatch repair complex. The inversion was shown to abolish MSH2 expression by both northern and western analysis. This study confirms that Southern blot analysis still represents a useful and informative tool to screen for and identify complex genomic rearrangements in HNPCC. Pathogenicity of the paracentric inversion was demonstrated by conversion analysis.
