For research use only (RUO). Not for use in diagnostics.
The SALSA MLPA Probemix P330 PCDH19 is a research use only (RUO) assay for the detection of deletions or duplications in the protocadherin-19 gene (PCDH19), which is associated with developmental and epileptic encephalopathy 9 (DEE9), also known as EIEE9 and EFMR.
DEE9 is characterised by seizure with onset in infancy or early childhood and cognitive impairment. Additional features include delayed development of variable severity, autistic signs and psychosis. Despite an X-linked mode of inheritance, which usually affects male carriers, this disease is restricted to females. This is probably due to a mechanism called cellular interference (Niazi et al. 2019). PCDH19 is subject to X-chromosome inactivation, which leads to a homogeneous population of cells negative for PCDH19 in males. In heterozygous females, on the other hand, the presence of both PCDH19-positive and PCDH19-negative cells affects the communication between the cells and leads to DEE9.
The PCDH19 gene (6 exons) spans ~119 kb of genomic DNA and is located on chromosome Xq22.1, ~99 Mb from the p-telomere.
SALSA MLPA Probemix P330 PCDH19 is for research use only (RUO) in all 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.
