Different brain regions were removed post mortem from three patients with the Lesch-Nyhan syndrome and were examined for alterations in hypoxanthine-guanine phosphoribosyl transferase (HGPRT), adenine phosphoribosyl transferase, and biochemical indexes of norepinephrine, dopamine, serotonin, gamma-aminobutyric acid (GABA), and acetylcholine neuron function, as compared with age-matched controls. The level of HGPRT activity in the material from patients with the Lesch-Nyhan syndrome was less than 1 per cent of control levels, whereas adenyl phosphoribosyl transferase was not significantly altered. All biochemical aspects of the function of dopamine-neuron terminals in the striatum (except dihydroxyphenylacetic acid levels) were decreased to 10 to 30 per cent of the control values. Serotonin and 5-hydroxyindoleacetic acid levels were increased, striatal choline acetyltransferase levels were low, and striatal glutamic acid decarboxylase and guanylate cyclase activities were unaltered. The disruption of the balance between the functions of GABA, dopamine, and acetylcholine neurons in the extrapyramidal system probably accounts for some of the symptoms observed in the Lesch-Nyhan syndrome (e.g., choreoathetosis).
