 Signs and symptoms typically appear during infancy or early childhood and can include feeding difficulties, lack of energy, low blood sugar (hypoglycemia), weak muscle tone (hypotonia), liver problems, and abnormalities in the retina. Later in childhood, people with this condition may experience muscle pain, breakdown of muscle tissue, and peripheral neuropathy. Individuals with LCHAD deficiency are also at risk for serious heart problems, breathing difficulties, coma, and sudden death. This condition is inherited in an autosomal recessive pattern and is caused by mutations in the HADHA gene. Treatment includes includes diet and low-dose carnitine supplements, as well as avoiding fasting.LCHAD deficiency, or long-chain 3-hydroxyacyl-CoA dehydrogenase deficiency, is a mitochondrial condition that prevents the body from converting certain fats to energy, particularly during periods without food (fasting).
