The SALSA MLPA Probemix P464 INSR is a research use only (RUO) assay for the detection of deletions or duplications in the INSR gene, which is associated with INSR-related severe syndromic insulin resistance.
INSR-related severe syndromic insulin resistance comprises a spectrum of milder to severe phenotypes, ranging from Donohue syndrome (most severe) to Rabson-Mendenhall syndrome (milder), based on the original clinical descriptions. Donohue syndrome is characterized by severe insulin resistance, severe growth failure, hypotonia, developmental delay, characteristic facial features and enlarged organs. Death usually occurs before the age of one. Rabson-Mendenhall syndrome is characterized by severe insulin resistance, with growth delay and intellectual disability varying from case to case. Facial features can be milder compared to Donohue syndrome. Life expectancy varies but death usually occurs in the second decade, most commonly because of complications of hyperglycemia. These disorders are extremely rare, with a prevalence estimated at under 1:1,000,000. INSR encodes the insulin receptor protein. This protein plays an important role in the insulin signalling pathway, which regulates glucose uptake and release, as well as the synthesis and storage of carbohydrates, lipids and protein.
The INSR gene (22 exons) spans ~182 kb of genomic DNA and is located on chromosome 19p13.2, ~7 Mb from the p-telomere.

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.
