Disorders of Gamma Aminobutyric Acid (GABA) Metabolism
Code E72.81, Disorders of gamma aminobutyric acid metabolism, was created for gamma aminobutyric acid (GABA) metabolism disorders. GABA is the major neurotransmitter that has the primary function of inhibiting activity of the central nervous system so that too many signals are not sent to the brain. It slows down the signals transmitted between neurons. The new code will allow the reporting of conditions that include succinic semialdehyde dehydrogenase deficiency (SSADHD) and GABA transaminase (GABA-T) deficiency. SSADHD is an autosomal recessive metabolic disorder that disrupts the normal metabolism of GABA so that GABA and the GABA derivative gamma-hydroxybutyric acid...
