Premium diagnostic services for ASM Deficiency
(Niemann-Pick Type A/B).
From enzyme and biomarker to genetic confirmation.

Path to ASMD Diagnosis

Our service is ideal for identification of ASM Deficiency (Niemann-Pick Type A/B) in at-risk patients showing specific clinical symptoms or for an individual or family member who has a family history of ASMD.

Testing is fast and safe using Dried Blood Spot (DBS) cards. This simple and minimally invasive technique supplies enough sample for biochemical testing and in most cases genetic confirmation testing as well.

About ASMD

What is ASM deficiency?

Acid Sphingomyelinase deficiency (ASM deficiency, ASMD), also known as Niemann-Pick Type A/B disease, is part of a group of lipid storage disorders affecting lipid metabolism in lysosomes. It is caused by a genetic mutation and results in a toxic accumulation of the metabolic substrate sphingomyelin.

Which mutation causes an enzyme deficiency?

ASMD is caused by different mutations in the SMPD1 gene. This gene is responsible for coding the ASM enzyme which metabolizes sphingomyelin. Accumulation of sphingomyelin, occurring primarily in the central nervous system, results in the clinical presentation of the disease.

Are there diseases similar symptoms to ASM deficiency?

Clinical presentation of ASM deficiency is similar to other congentital sphingolipidoses which can result in underdiagnosis. For example, recent evidence has shown that 1 in 5 patients suspected of Gaucher disease is actually affected with ASMD[1].
