Diagnosis through genetic testing can strongly help uncover the cause of persistent, often debilitating, undiagnosed symptoms in patients suffering with suspected genetic metabolic disorders. With knowledge of variants in over 1,250 metabolic disease genes, our rapid testing and extensive experience of metabolic disease genetics can help you diagnose and manage your patients’ metabolic disorder quickly and correctly. Ultimately this can provide new insights into treatment options and predict the likelihood of passing the inherited condition on to offspring or the presence of it elsewhere in the family.

The use of personalized medicine to treat rare monogenic diseases like lysosomal storage disorders (LSDs) is challenged by complex clinical trial designs, high costs, and low patient numbers. Hundreds of mutant alleles are implicated in most of the LSDs. The diseases are typically classified into 2…
Glucosylceramide and glucosylsphingosine are the two major storage products in Gaucher disease (GD), an inherited metabolic disorder caused by a deficiency of the lysosomal enzyme glucocerebrosidase. The pathological role of the deacylated form of glucosylceramide, glucosylsphingosine (lyso-Gb1), a…
Lyso-SM-509 Is a Highly Specific and Sensitive Biomarker for the Identification of Niemann-Pick Patients: a 30 Months Study
We present data from a 2 year global cohort of Niemann Pick patients using lyso-SM-509 biomarker determination, followed by sequencing of NPC1/2 genes. Determination of lyso-SM-509 is performed by LC/MRM-MS in plasma, serum, EDTA blood anddried blood spots (DBS). We identified in a world-wide study…
The new biomarker can be determined directly in the dried blood spot (DBS) extract with low sample consumption, easy sample preparation, high reproducibility and it presents the possibility of being used in high throughput screenings.
Glucosylsphingosine (lyso-Gb1) Plays a Central Role in the Diagnosis and Proper Assessment of Disease Severity in Gaucher Patients
We have developed and systematically validated a high-throughput workflow for the simple testing of GD patients: beta-glucocerebrosidase enzymatic activity, glycosylsphingosine (lyso-Gb1) quantification in DBS followed by GBA gene sequencing from the sample blood sample. We report data from over 940…
