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.

Reductions in glucosylsphingosine (lyso-Gb1) in treatment-naïve and previously treated patients receiving velaglucerase alfa for type 1 Gaucher disease
Gaucher disease (GD), an autosomal recessive lipid storage disorder, arises from mutations in the GBA1 (β-glucocerebrosidase) gene, resulting in glucosylceramide accumulation in tissue macrophages. Lyso-Gb1 (glucosylsphingosine,lyso-GL1), a downstream metabolic product of glucosylceramide, has been…
Farber disease (FD) is a rare autosomal recessive disease caused by mutations in the acid ceramidase gene (ASAH1). Low ceramidase activity results in the accumulation of fatty substances, mainly ceramides. Hallmark symptoms at clinical level are periarticular nodules, lipogranulomas, swollen and…
