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

Deoxysphingolipids (dSLs) are elevated in patients with hereditary sensory and autonomic neuropathy type I (HSAN1) due to variants in SPTLC1 and SPTLC2, and are useful to support a diagnosis of HSAN1.

 

Elevations in dSLs may also be seen in patients with order disorders including type 2 diabetes, metabolic syndrome, mitochondrial disease, glycogen storage disease type I, and possibly disorders of serine biosynthesis.

 

Additional testing is required to determine the specific cause of elevated dSLs.
