Abstract

We evaluated electron transport chain activity in platelet mitochondria taken from HD patients. All 5 patients studied had striking depressions of NADH: ubiquinone oxidoreductase activity (complex I) (5.36 ± 2.91 nmol/min/mg; control mean, 19.12 ± 5.64 nmol/min/mg). Other electron transport chain activities were not significantly different from control values. HD may be caused by a mutation in 1 of the nuclear coded subunits of NADH: ubiquinone oxidoreductase.
