Overview

Dihydrolipoamide dehydrogenase (DLD) deficiency is a very rare condition that can vary in age of onset, symptoms and severity. The condition may be characterized by early-onset lactic acidosis and delayed development (most commonly); later-onset neurological dysfunction; or adult-onset isolated liver disease. Signs and symptoms may include lactic acidosis shortly after birth; hypotonia and lethargy in infancy; feeding difficulties; seizures; and various other health issues. Liver problems can range from hepatomegaly to life-threatening liver failure. Symptoms often occur in episodes that may be triggered by illness or other stresses on the body. Many affected infants do not survive the first few years of life; those who survive through early childhood often have growth delay and intellectual disability. Some with onset later in childhood may have neurological dysfunction with normal cognitive development. DLD deficiency is caused by mutations in the DLD gene and is inherited in an autosomal recessive manner.[1][2][3]
