Biochemical markers for Huntington's chorea.
The uptake of dopamine (DA) by platelet rich plasma was assayed in 11 patients with Huntington's chorea (H.C.). The results confirmed the previous observation that platelets from H.C. patients take up, at equilibrium, more dopamine than do platelets from normal control subjects. The mean difference was 50% higher at DA substrate concentrations of 0.11 mM. However, attempts to confirm the higher Na+ - K+ ATPase activity of erythrocyte ghosts from Huntington's chorea patients were unsuccessful.
