Alpha Amino Adipic Semialdehyde (Random Urine)
Alias: AASA
Discipline: Clinical Chemistry
Test information: Pyridoxine-dependent epilepsy is an autosomal recessive disease caused by mutations in the alpha-aminoadipic semialdehyde (AASA) dehydrogenase gene on chromosome 5q31. Deficiency of the enzyme leads to the accumulation of AASA and piperideine- 6-carboxylate (P6C), elevated levels of which can be detected in urine, plasma, and CSF of affected patients. Patients usually present with neonatal seizures that are unresponsive to conventional anti-convulsant therapy.
