The SALSA MLPA Probemix P366 CHM-RP2-RPGR is a research use only (RUO) assay for the detection of deletions or duplications in the CHM, RP2 and RPGR genes, which are associated with X-linked retinitis pigmentosa and choroideremia.
Retinitis pigmentosa (RP) (prevalence 1/4000) is a hereditary degenerative disease of the photoreceptor neurons of the retina. RP is characterized by progressive degeneration of the peripheral retina (leading to night blindness), loss of the peripheral visual field and an abnormal electroretinogram. X-linked Retinitis Pigmentosa (xlRP) accounts for 5-15% of all RP syndromes. Mutations in the RPGR (also called RP3) and RP2 genes are the most common causes of xlRP, responsible for 70-90% and 10-20% of the xlRP cases, respectively.
Choroideremia (CHM) is another X-linked recessive retinal degeneration disease which could be confused with X-linked retinitis pigmentosa. CHM is a rare inherited disorder that causes progressive loss of vision due to degeneration of the choroid and retina. This progressive X-linked retinopathy is caused by the deletion of the CHM gene which encodes the Rab escort protein1 (REP1). REP1 is involved in the prenylation of Rabs. Under-prenylation of Rabs could affect vesicular trafficking, exocytosis and secretion in peripheral cells of CHM patients.
The RPGR gene (19 exons) spans ~58 kb of genomic DNA and is located on Xp11.4, 38 Mb from the p-telomere.The RP2 gene (5 exons) spans ~45 kb of genomic DNA and is located on Xp11.3, 47 Mb from the p-telomere.The CHM gene (16 exons) spans ~186 kb of genomic DNA and is located on Xq21.2, 85 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.
