Long-chain 3-hydroxyacyl-coa dehydrogenase deficiency
Type of disease: Rare conditions
LCHAD deficiency, or long-chain 3-hydroxyacyl-CoA dehydrogenase deficiency, is a rare inherited condition that prevents the body from converting certain fats to energy, particularly during periods without food (fasting). 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.
