Objectives:
TANGO2 deficiency is a rare inborn error of metabolism, with distinct clinical features. The clinical presentations of TANGO2 deficiency are developmental delay, speech difficulties, intellectual disability, non-life-threatening paroxysmal neurologic episodes (TANGO2 spells), acute metabolic crises, cardiac crises, seizures and hypothyroidism. Patients may die in acute metabolic crises. Here we report our experience in the management of an acute metabolic crisis in TANGO2 deficiency.
Case Presentation:
A 9-year-old patient diagnosed with TANGO2 deficiency was admitted with fever, fatigue, unable to walk. In follow up, encephalopathy, rhabdomyolysis and arrhythmia were detected. Vitamin B-complex was started. Our patient's mental status and rhabdomyolysis improved dramatically, and cardiac crises ended without Torsades de pointes, ventricular tachycardia and/or fibrillation or myocardial dysfunction.
Conclusions:
With this report, we aimed to show the effectiveness of vitamin B-complex in the management of acute metabolic crises.
Insights
Vitamin B-complex effectively managed acute metabolic crises in TANGO2 deficiency, a rare inborn error of metabolism. This treatment improved neurological and cardiac symptoms, preventing severe complications in a pediatric patient.
Area of Science:
- Biochemistry
- Genetics
- Pediatric Neurology
Background:
- TANGO2 deficiency is a rare inborn error of metabolism.
- Clinical features include developmental delay, intellectual disability, seizures, and acute metabolic/cardiac crises.
- Acute crises can be fatal if not managed promptly.
