SALSA® MLPA® Probemix P017 MEN1 detects copy number variations in the MEN1 gene.
Contents: 25 MLPA probes, including 15 probes for the MEN1 region (covering all 10 exons).
Tissue: genomic DNA isolated from human peripheral whole blood.
Application: multiple endocrine neoplasia type 1 (MEN1).
CE-marked and registered for in vitro diagnostic (IVD) use in selected territories.
The SALSA MLPA Probemix P017 MEN1 is an in vitro diagnostic (IVD) or research use only (RUO) semi-quantitative assay for the detection of deletions or duplications in the MEN1 gene in genomic DNA isolated from human peripheral whole blood specimens. P017 MEN1 is intended to confirm a potential cause for and clinical diagnosis of multiple endocrine neoplasia type 1 (MEN1) and for molecular genetic testing of at-risk family members.
For the full intended purpose, see the product description.
Multiple endocrine neoplasia (MEN) is an autosomal dominant cancer predisposition syndrome characterized by tumours found in two or more endocrine glands. MEN type 1 (MEN1) is primarily characterized by the occurrence of primary hyperparathyroidism (PHPT), which occurs in 95-100% of patients; pancreatic neuroendocrine tumours, which occur in 40-75% of patients; and pituitary adenoma, which is found in 30-50% of patients. Additionally, adrenal tumours, duodenal, thymic and lung neuroendocrine tumours, lipomas, facial angiofibroma, and collagenoma can be found. Most tumours are non-metastasizing, but many can cause striking and serious clinical effects due to increased secretion of hormones. It is estimated that in the general population 1 to 10 in 100.000 individuals develop MEN1 during their lifetime. Nine out of ten patients diagnosed with MEN1 have the familial form, and the penetrance is >95% by age 40 for confirmed pathogenic mutations. The mean age of death of MEN1 patients is between 50 and 55 years of age.
The single gene associated with MEN1 syndrome is MEN1. Heterozygous MEN1 pathogenic variants are found in ~90% of familial MEN1 syndrome patients and in ~65% of sporadic cases. Loss of heterozygosity (LOH) is frequently observed in MEN1 tumours suggesting that MEN1 acts as a tumour suppressor gene, as postulated by the Knudson 2-hit hypothesis. Besides point mutations, several deletions involving one or more complete exons in the MEN1 gene have been described (Carroll 2013, Concolino et al. 2016, Lemos and Thakker 2008, Romanet et al. 2019, Thakker 2014), including a pathogenic deletion of just the 5’-UTR (Kooblall et al. 2020).
Please note that this probemix is not suited to detect deletions or duplications in DNA extracted from fresh tumour tissue or from formalin-fixed paraffin embedded (FFPE) tumour materials. Probemix P244 (only version D1) can be used in a research setting to detect CNVs in the MEN1-region in DNA from tumour material.
SALSA MLPA Probemix P017 MEN1 is CE-marked for in vitro diagnostic (IVD) use. This assay has also been registered for IVD use in Israel.
This assay is for research use only (RUO) in all other territories.
A general SALSA MLPA Reagent Kit is required for MLPA experiments (to be ordered separately).

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.
We have no information about specific commercially available positive samples that can be used with this product.
