Intended purpose

The SALSA MLPA probemix P248 MLH1-MSH2 Confirmation is an in vitro diagnostic (IVD) or research use only (RUO) semi-quantitative assay for the detection of deletions or duplications in the MLH1 and MSH2 genes in genomic DNA isolated from human peripheral whole blood specimens. P248 MLH1-MSH2 Confirmation is intended to confirm a potential cause for and clinical diagnosis of Lynch syndrome, as initially determined using the SALSA MLPA probemix P003 MLH1/MSH2. P248 MLH1-MSH2 Confirmation cannot be used to verify deletions or duplications in EPCAM detected by P003 MLH1/MSH2.

For the full intended purpose, see the product description.

Clinical background

Lynch syndrome, formerly known as hereditary non-polyposis colorectal cancer (HNPCC), is an adult-onset hereditary cancer susceptibility syndrome predisposing to several cancer types, the most prevalent being colorectal cancer, endometrial cancer, ovarian cancer, gastric cancer and small bowel cancer. It is an autosomal dominantly inherited syndrome that is caused by heterozygous germline mutations in one of the four major DNA mismatch repair genes: MLH1, MSH2, MSH6 or PMS2. Another cause of Lynch syndrome is a deletion of the 3’ part of EPCAM, leading to constitutional epigenetic silencing of the downstream MSH2 gene (Lynch et al. 2015). The estimated contribution of the different genes to Lynch syndrome is 15-40% for MLH1, 20-40% for MSH2, 12-35% for MSH6, 5-25% for PMS2 and <10% for EPCAM. More information about Lynch syndrome is available on http://www.ncbi.nlm.nih.gov/books/NBK1211/.

Among the various defects in the MLH1 and MSH2 genes that have been found in patients, deletions and duplications of complete exons are usually missed by standard sequence analysis. The MLPA technique can detect most of these deletions and duplications and therefore complements sequence analysis of the MLH1 and MSH2 genes.

How to Order

Positive samples

Inclusion of a positive sample is usually not required, but can be useful for the analysis of your experiments. MRC Holland has very limited access to positive samples and cannot supply such samples. We recommend using positive samples from your own collection. Alternatively, you can use positive samples from an online biorepository, such as the Coriell Institute.

See this support article for commercially available positive samples that have been tested with this product.
