Test ID: LSD6W    
Lysosomal Storage Disorders, Six-Enzyme Panel, Leukocytes

Useful For Suggests clinical disorders or settings where the test may be helpful

Diagnosis of the lysosomal storage disorders: Fabry (in male patients), Gaucher, Krabbe, mucopolysaccharidosis I (MPS I), Niemann-Pick types A and B, and Pompe (Glycogen storage disorder type II)

 

This test is not intended for carrier detection

Genetics Test Information Provides information that may help with selection of the correct genetic test or proper submission of the test request

Lysosomal storage disorders are a diverse group of inherited diseases characterized by the intracellular accumulation of macromolecules leading to cell damage and organ dysfunction.

 

Due to the improved outcomes associated with presymptomatic intervention, some states have recently added select lysosomal storage disorders to their newborn screening programs.

 

This test is an enzyme testing panel for individuals with positive newborn screen results or clinical signs and symptoms suspicious for Fabry disease, Gaucher disease, Krabbe disease, mucopolysaccharidosis I, Niemann-Pick A/B disease or Pompe disease. If an enzyme deficiency is detected by this screening test, additional biochemical or molecular testing is required to confirm a diagnosis.
