SALSA MLPA Probemix P338 GBA

Gaucher disease

Region: GBA 1q22

This product is for basic research and intended for experienced users only! Interpretation of results may be complicated, and MRC Holland may only be able to provide basic support.

General information
The SALSA MLPA Probemix P338 GBA is a research use only (RUO) assay for the detection of deletions or duplications in the GBA gene, which is associated with Gaucher disease. This probemix can also be used to detect the presence of the 55-bp deletion (c.1265_1319del) in GBA exon 9 and the c.1448T>C point mutation (p.L444P; also known as p.L483P) in GBA exon 10.

Gaucher disease is an autosomal recessive lysosomal storage disorder that is caused by a deficiency in beta-glucocerebrosidase enzyme activity. Beta-glucocerebrosidase is a lysosomal protein that cleaves the beta-glucosidic linkage of glucosylceramide (GlcCer, glucosylcerebroside), an intermediate in glycolipid metabolism. As a result of beta-glucocerebrosidase deficiency, there is intracellular accumulation of glucosylceramide primarily within cells of mononuclear phagocyte origin. This accumulation of fatty materials transforms the cells into so-called ‘Gaucher cells’ with a characteristic crumpled tissue paper appearance. Beta-glucocerebrosidase is encoded by the GBA gene on chromosome 1q22. Defects in the GBA gene are the main cause of Gaucher disease.

Probemix content
The SALSA MLPA Probemix P338-B2 GBA contains 23 MLPA probes with amplification products between 155 and 363 nucleotides (nt). This includes nine probes for the GBA gene and three flanking probes. The GBA exon 9 probe will generate a lower signal when the 55-bp deletion (c.1265_1319del) is present. The GBA exon 10 probe will generate a lower signal when the c.1448T>C mutation (p.L444P; also known as L483P) is present. In addition, 11 reference probes are included that detect autosomal chromosomal locations. Complete probe sequences and the identity of the genes detected by the reference probes are available online (www.mrcholland.com).

This probemix contains nine quality control fragments generating amplification products between 64 and 105 nt: four DNA Quantity fragments (Q-fragments), two DNA Denaturation fragments (D-fragments), one Benchmark fragment, and one chromosome X and one chromosome Y-specific fragment. More information on how to interpret observations on these control fragments can be found in the MLPA General Protocol and online at www.mrcholland.com.
