Multiple Acyl-CoA Dehydrogenase Deficiency: Symptoms & Treatment
Written by Medicover Team and Medically Reviewed by Dr Anusha Bandaru , General Medicine
Table of Contents
Multiple Acyl-CoA Dehydrogenase Deficiency (MADD) is a rare genetic disorder that affects the body's ability to break down certain fats and proteins for energy. This condition leads to a disruption in the normal metabolic processes, causing a buildup of toxic substances in the body.
As a result, individuals with MADD may experience various health complications due to the impaired energy production and accumulation of harmful byproducts. The impact of MADD on health can vary depending on the severity of the condition and individual factors.
What Are the Types of Multiple Acyl-CoA Dehydrogenase Deficiency?
Multiple Acyl CoA dehydrogenase deficiency can present in different forms, affecting various organs and systems in the body.
- Neonatalonset Multiple AcylCoA Dehydrogenase Deficiency (MADD): Presents in newborns with severe symptoms such as metabolic crisis and respiratory distress.
- Lateonset Multiple AcylCoA Dehydrogenase Deficiency (MADD): Symptoms manifest later in childhood or adulthood and vary in severity, including muscle weakness and exercise intolerance.
- Mild Multiple AcylCoA Dehydrogenase Deficiency (MADD): Characterized by milder symptoms that may go undiagnosed until adulthood, such as fatigue and muscle pain.
- Severe Infantileonset Multiple AcylCoA Dehydrogenase Deficiency: Occurs in infants and leads to rapid deterioration, metabolic crisis, and multiorgan failure.
- Atypical Multiple AcylCoA Dehydrogenase Deficiency: Rare variant with unique clinical features that may not fit the typical presentation of other types of MADD.
What are the Symptoms of Multiple Acyl Coa Dehydrogenase Deficiency?
Multiple Acyl coA dehydrogenase deficiency typically presents with a range of symptoms affecting various body systems.
- Muscle weakness
- Lethargy
- Hypoglycemia
- Metabolic acidosis
- Heart problems
- Respiratory distress
- Liver dysfunction
- Enlarged liver and spleen
- Developmental delays
- Seizures
What Causes Multiple Acyl-CoA Dehydrogenase Deficiency?
Multiple Acyl-CoA dehydrogenase deficiency is primarily caused by genetic mutations that affect the enzymes responsible for breaking down fats for energy production in the body. Causes of Multiple Acyl CoA Dehydrogenase Deficiency:
- Genetic mutations in genes related to electron transfer flavoprotein (ETF) or ETF dehydrogenase (ETFDH).
- Inheritance of the disorder from parents who are carriers of the mutated genes.
- Factors that trigger metabolic stress, such as fasting or infections, leading to symptoms in affected individuals.
When Should You See a Doctor for Multiple Acyl-CoA Dehydrogenase Deficiency?
Consult a general physician if you or your child experience unexplained muscle weakness, repeated episodes of low blood sugar, developmental delays, or symptoms that worsen during illness or fasting.
- Recurrent low blood sugar
- Persistent muscle weakness or fatigue
- Difficulty feeding or poor growth in infants
- Developmental delay
- Seizures
- Breathing difficulties
- Recurrent metabolic crises during illness
Early diagnosis and treatment can help prevent serious complications and improve long-term health outcomes.

How Is Multiple Acyl-CoA Dehydrogenase Deficiency Diagnosed?
Multiple Acyl-CoA Dehydrogenase Deficiency is typically diagnosed through a combination of clinical symptoms, laboratory tests, and genetic analysis.
- Blood Tests
- Urine Tests
- Genetic Testing
- Muscle Biopsy
What Are the Treatment Options for Multiple Acyl-CoA Dehydrogenase Deficiency?
Multiple Acyl CoA dehydrogenase deficiency is generally managed through a combination of supportive care and specific interventions to address metabolic abnormalities.
- Dietary Management: A lowfat, highcarbohydrate diet supplemented with mediumchain triglycerides (MCT) can help manage symptoms and provide energy to the body.
- Supplementation: Carnitine and riboflavin supplements may be prescribed to support energy production and improve muscle function in individuals with Multiple Acyl coA dehydrogenase deficiency.
- Avoid Fasting: Preventing long periods of fasting and ensuring regular meals or snacks can help maintain stable blood sugar levels and prevent metabolic crises.
- Medical Monitoring: Regular monitoring of blood sugar, amino acids, and organic acids can help track the progression of the disease and guide treatment adjustments.
- Symptomatic Treatment: Depending on the individual's symptoms, treatments such as physical therapy, respiratory support, and cardiac monitoring may be necessary to manage complications of Multiple Acyl coA dehydrogenase deficiency.
