Primary muscle coenzyme Q10 (CoQ10) deficiency is an apparently autosomal recessive condition with heterogeneous clinical presentations. Patients with these disorders improve with CoQ10 supplementation. In a family with ataxia and CoQ10 deficiency, analysis of genome-wide microsatellite markers suggested linkage of the disease to chromosome 9p13 and led to identification of an aprataxin gene (APTX) mutation that causes ataxia oculomotor apraxia (AOA1 [MIM606350]). The authors' observations indicate that CoQ10 deficiency may contribute to the pathogenesis of AOA1.
