Biomarker and biochemical testing
An ideal biomarker plays an essential role in the early diagnosis, prediction and therapeutic monitoring of a specific disease, reflecting the burden of the disease for the patients.
Using a biomarker either as a diagnosis tool for lysosomal storage diseases, or in regular monitoring of the disease progression, can be of high clinical value for the patients. Biomarkers bring rationality in the treatment of patients with rare diseases, and can be used as a measure of the therapy efficacy and even as a guide for therapy dosage.
Biomarkers transform the management of lysosomal storage disorders (LSD)
CENTOGENE's biomarker pipeline, CentoGuard, reflects the increasing demand for highly sensitive, superior biomarkers for individual therapy monitoring in the orphan drug market.

CENTOGENE works alongside academic and industrial partners, as well as patient organizations to develop new diagnostic assays and biomarkers that can improve the condition and prospects of patients affected by lysosomal storage disorders.
Application of CENTOGENE’s CE-labeled biomarkers
CentoGaucher, CentoFabry, CentoFarber and CentoNPC are the first CE-labeled test methods for exact measuring the biomarker in Gaucher, Fabry, Farber's disease as well as Niemann-Pick disease type C. They are developed as easy and fast screening techniques for measuring the biomarker levels in affected patients based on tandem mass spectrometry (MRM-MS).
Using the example of Gaucher disease, CentoGaucher measures the biomarker level of the lyso-glucosylsphingosine (lyso-Gb1) concentration in Gaucher patients. Lyso-Gb1 reflects perfectly the severity of the disease, correlates with the progress and reflects the extent of improvement once the patients are set on treatment.
Lyso-Gb1 demonstrates the highest sensitivity and specificity for diagnosis and monitoring of Gaucher disease (Rolfs et al. 2013). High lyso-Gb1 levels indicate a disease crisis. In this particular case, a bone crisis was present in 3/2015 and 7/2015. ▼
A significant increase of lyso-Gb1 level demonstrated that the dosage of the enzyme replacement therapy (ERT) had to be adjusted. After ERT adjustment, the lyso-Gb1 level decreased to an almost normal level.
CENTOGENE has developed targeted biomarker ID cards which allow the continuous documentation of lyso-Gb1 levels in your patients. Only regular monitoring of the lyso-Gb1 level (recommended each quarter) will ensure an effective dosage under enzyme replacement therapy in your Gaucher patients.

GM1 gangliosidosis is a rare lysosomal storage disorder characterized biochemically by deficient beta-galactosidase activity and clinically by a wide range of variable neurovisceral, ophthalmological and dysmorphic features. GM1 gangliosidosis, also known as GLB1 deficiency, is estimated to occur in…
Niemann-Pick disease (NPD) is a lipid storage disorder that results from the deficiency of a lysosomal enzyme, acid sphingomyelinase. Niemann-Pick disease type C is due to variants in one of two different genes, NPC1 and NPC2. It is characterized by progressive neurodegeneration with an estimated…
Gaucher disease is a rare genetic disorder characterized by the deposition of glucocerebroside in cells of the macrophage-monocyte system. The disorder results from the deficiency of the enzyme glucocerebrosidase. The prevalence of GD is approximately 1 in 57,000 to 1 in 75,000 worldwide but the…
