Common Name | 2-Hydroxyadipic acid |

Description | 2-Hydroxyadipic acid is a hydroxy-dicarboxylic acid formed by the reduction of 2-ketoadipic acid. A deficiency of 2-ketoadipic dehydrogenase causes 2-ketoadipic acidemia or 2-oxoadipic acidemia (OMIM: 245130 ), A genetic disorder characterized by accumulation and excretion of 2-hydroxyadipic acid (with 2-ketoadipic and 2-aminoadipic) (OMMBID - The Online Metabolic and Molecular Bases of Inherited Disease, CH.95). When present in sufficiently high levels, 2-hydroxyadipic acid can act as an acidogen and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of 2-hydroxyadipic acid are associated with at least three inborn errors of metabolism including 2-oxoadipic acidemia, 2-aminoadipic aciduria, and 2-oxoadipic aciduria. 2-Hydroxyadipic acid is an organic acid. Abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). These can progress to heart abnormalities, kidney abnormalities, liver damage, seizures, coma, and possibly death. These are also the characteristic symptoms of the untreated IEMs mentioned above. Many affected children with organic acidemias experience intellectual disability or delayed development. In adults, acidosis or acidemia is characterized by headaches, confusion, feeling tired, tremors, sleepiness, and seizures. |
