Most often, the parents of an individual with an autosomal recessive disorder each carry one copy of the altered gene but do not show signs and symptoms of the disorder. 3-hydroxyacyl-coenzyme A dehydrogenase deficiency 3-hydroxyacyl-coenzyme A dehydrogenase deficiency (HADH deficiency) is a rare condition that prevents the body from converting certain fats to energy, particularly during
