Decarboxylase Deficiency

AbstractAromatic L-amino acid decarboxylase (AADC) deficiency is an autosomal recessive metabolic disorder resulting from disease-causing pathogenic variants of the dopa decarboxylase (DDC) gene. The neurological features of AADC deficiency include early-onset hypotonia, oculogyric crises, ptosis, dystonia, hypokinesia, impaired development, and autonomic dysfunction. We report a patient with genetically confirmed AADC deficiency presenting with developmental epileptic encephalopathy (DEE). We report a boy with severe intractable epileptic spasms and DEE. The patient was evaluated for cognitive and neurologic impairment. Exome sequencing revealed a homozygous mutation (NM_000790.4:c.121C > A; p.Leu41Met) in the DDC gene. This case expands the clinical spectrum of AADC deficiency and strengthens the association between dopa decarboxylase deficiency and epilepsy. Additional studies are warranted to clarify the mechanisms linking dopa decarboxylase dysfunction to DEE.

Decarboxylase Deficiency

AbstractAromatic L-amino acid decarboxylase (AADC) deficiency is a rare, autosomal recessive inborn error of metabolism in which several neurotransmitters including serotonin, dopamine, norepinephrine and epinephrine are deficient. Symptoms typically appear in the first year of life and include oculogyric crises and dystonia, hypotonia, and global developmental delay. Dystonia is of particular concern as a dystonic storm can ensue leading to rhabdomyolysis. Rhabdomyolysis can become life-threating and therefore its recognition and prompt management is of significant importance. Here we present two cases of patients with AADC deficiency and a history of dystonic crisis causing rhabdomyolysis. We hypothesize that in addition to the hypodopaminergic, a hypercholinergic state is contributing to the pathophysiology of dystonia in AADC deficiency, as well as to the associated rhabdomyolysis. We were able to prevent rhabdomyolysis in both patients with using Dantrolene and we suggest using a trial of this medication in cases of sustained dystonic crisis in AADC deficiency patients.
