Enquire About This Test

What does this test assess?

This method detects specific biomarkers for adenylosuccinate lyase (ADSL) deficiency and ATIC deficiency, two rare but clinically significant disorders of de novo purine synthesis.

Clinical indications include:

  • Diagnosis of adenylosuccinate lyase (ADSL) deficiency
  • Diagnosis of AICA-ribosiduria (ATIC deficiency)
  • Investigation of unexplained intellectual disability with epilepsy
  • Screening in consanguineous families with developmental delay

Measured analytes

Analyte coverage

SAICAR (succinylaminoimidazole carboxamide riboside) and succinyladenosine (S-Ado).

Analytical technique

Both analytes are measured simultaneously by LC-MS/MS from a single urine sample, providing high sensitivity and specificity for these rare disorder-specific biomarkers.
