The SALSA MLPA Probemix P176 CAPN3 is a research use only (RUO) assay for the detection of deletions or duplications in the CAPN3 gene, which is associated with limb-girdle muscular dystrophy type 2A (LGMD2A).
Limb-girdle muscular dystrophies (LGMD) are a group of phenotypically and genotypically heterogeneous diseases, characterised by progressive weakness and atrophy of the muscles of the pelvic and shoulder girdle. Mutations of the CAPN3 gene have been associated with limb-girdle muscular dystrophy type 2A (LGMD2A), also called calpainopathy. Patients with LGMD2A have symmetrical and selective involvement of proximal limb-girdle muscles. The disease shows wide intrafamilial and interfamilial clinical variability. The age at onset ranges from 2 to 40 years, but the disease usually first appears in the second or third decade of life, with the development of proximal weakness in the lower limbs. Mutations in CAPN3 result in a cascade of events leading eventually to muscular dystrophy, but the precise underlying mechanisms have yet to be elucidated. However, a defect in proteolytic activity of calpain 3, the protein encoded by CAPN3, is largely recognised as the main pathogenic cause of LGMD2A.
The CAPN3 gene (24 exons) spans ~53 kb of genomic DNA and is located on chromosome 15q15.1, ~40 Mb from the p-telomere. The gene is predominantly expressed in skeletal muscle where it is present in the cytosol as well as in the nucleus. The protein encoded by this gene (calpain 3) belongs to the superfamily of calcium-activated neutral proteases, which are non-lysosomal intracellular cysteine proteases. Calpains respond to Ca2+ signals by cleaving specific proteins, frequently components of signalling cascades, thereby irreversibly modifying their function(s).

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.
