L-2-hydroxyglutaric aciduria is an inherited metabolic condition that is associated with progressive brain damage. Signs and symptoms of this condition typically begin during infancy or early childhood and may include developmental delay, seizures, speech difficulties, macrocephaly and abnormalities in a part of the brain called the cerebellum, which is involved in coordinating movement (i.e. balance and muscle coordination). L-2-hydroxyglutaric aciduria is caused by changes (mutations) in the L2HGDH gene and is inherited in an autosomal recessive manner.[9883][9888] Treatment is focused on alleviating the signs and symptoms of the condition, such as medications to control seizures.[9887]
