Very long chain Acyl-CoA dehydrogenase deficiency (VLCADD) is a genetic condition in which the body cannot break down certain fats into energy. In this handout, you will learn a care plan if your child with VLCADD gets sick.

If you need to go to the emergency room, take this handout with you. Give it to the doctor so they can care for your child.

When to Call the Genetics and Metabolism Doctor

Fasting or long periods of time without food can lead to metabolic decompensation. Seizures or coma can develop 1-2 hours after symptoms start.

When a child with VLCADD gets sick there are specific signs to look for that require further evaluation by a doctor, such as:

  • Lethargy (extreme lack of energy)
  • Vomiting or nausea
  • Unwillingness or inability to eat, even when sick
  • Signs of low blood sugar (shaking, chills, sweating)
  • Chest pain
  • Seizures or coma
