Intended purpose

The SALSA MLPA Probemix P378 MUTYH is an in vitro diagnostic (IVD) or research use only (RUO) semi-quantitative assay for the detection of deletions or duplications in the MUTYH gene, as well as the presence of the two most common point mutations among people of European descent, c.536A>G (p.Tyr179Cys) and c.1187G>A (p.Gly396Asp), in order to confirm a potential cause and clinical diagnosis of MUTYH-Associated Polyposis (MAP). In addition, P378 MUTYH can be used to detect duplications in the SCG5/GREM1 region in order to confirm a potential cause and clinical diagnosis of Hereditary Mixed Polyposis Syndrome type 1 (HMPS1). This assay is also intended for molecular genetic testing of at-risk family members. P378 MUTYH is for use with genomic DNA isolated from human peripheral whole blood specimens.

For the full intended purpose, see the product description.

Clinical background

Mutations in the MUTYH gene result in a hereditary predisposition to colon and gastric cancer, which is referred to as MAP. MAP is an autosomal recessive disorder. In MAP patients, ten to several hundred colonic adenomatous polyps develop, and these become evident at a mean age of 50 years. However, colon cancer can also develop in the absence of polyposis. A single defective copy of the MUTYH gene may result in no, or only a small increase in risk for colorectal cancer (CRC). There are two common MUTYH mutations, c.536A>G (p.Tyr179Cys) and c.1187G>A (p.Gly396Asp) that are carried by ~1%-2% of the general population and account for ≥90% of all MUTYH pathogenic variants in northern European populations. Up to 70% of MAP patients harbor at least one of these variants (Aretz et al. 2013). Copy number variations of MUTYH are very rare; they account for <1% of pathogenic alleles. The most frequent CNV in MUTYH - a deletion of exon 4-16 - is reported in multiple patients (Castillejo et al. 2014). More information on MAP is available at http://www.ncbi.nlm.nih.gov/books/NBK107219/.

A recurrent duplication of ~40 kb directly upstream of the GREM1 gene is known to lead to HMPS1. Patients with HMPS1 have a predisposition for developing CRC (Jaeger et al. 2012). Presence of this duplication is predicted to cause reduced bone morphogenetic protein (BMP) pathway activity, a mechanism that underlies tumorigenesis in juvenile polyposis of the large bowel. Several additional duplications in the GREM1 upstream region have been found: e.g. a duplication of the upstream region and the whole GREM1 gene of ~57 kb has been described in one patient with sigmoid colon carcinoma (Venkatachalam et al. 2011); a duplication of ~16 kb has been described in members of a family presenting with atypical FAP (Rohlin et al. 2016); and a duplication of ~24 kb in a patient with multiple colon polyps has been reported (McKenna et al. 2019). These different duplications can be detected by multiple probes in this P378-D1 probemix as is indicated in the table below. More information on HMPS1 is available at http://omim.org/entry/601228.

Regulatory status

SALSA MLPA Probemix P378 MUTYH is CE-marked for in vitro diagnostic (IVD) use. This assay has also been registered for IVD use in Colombia and Israel.

This assay is for research use only (RUO) in all other territories.

SALSA Sample DNA for this product

SALSA Binning DNA SD022 is an artificial DNA sample with a signal for all probes in the P378 MUTYH probemix. Inclusion of a reaction with SD022 in initial experiments and in experiments following a change in electrophoresis conditions is recommended to aid in the creation of a bin set that links peaks to the probes that produce them. Binning DNA cannot be used as a reference sample in the MLPA data analysis, and cannot be used to quantify the signals of mutation-specific probes.

A vial of SALSA Binning DNA SD022 is included with every order of the P378 MUTYH probemix, but it is possible to order additional vials separately.

For more information, see the product description.

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.
