Abstract

We analyzed the gene encoding the 24-kDa subunit of mitochondrial complex I, which has been implicated in the pathogenesis of Parkinson disease (PD). We set out to identify a polymorphism in the 24-kDa subunit gene (NDUFV2) in patients with PD and determine whether genetic polymorphism of this gene is associated with a higher risk of PD. The subjects comprised 126 patients with PD, and the control group comprised 113 unrelated individuals without neurodegenerative disorders. A novel polymorphism (Ala29Val) in the mitochondrial targeting sequence of NDUFV2 was found in patients with PD. The distribution of the three genotypes was significantly different between the two groups (χ2= 7.53,df= 2,P= 0.023). The frequency of homozygotes for the mutation was significantly higher in PD patients (23.8%) than in control subjects (11.5%, Fisher's exact test,P= 0.0099 < 0.01). The risk of developing PD associated with homozygosity for this mutation was calculated as 2.40 (95% CI: 1.18–4.88). NDUFV2 constitutes one genetic risk factor for PD, and the mutation may well be a cause of complex I deficiency in this disease.

<ce:simple-para>We analyzed the gene encoding the 24-kDa subunit of mitochondrial complex I, which has been implicated in the pathogenesis of Parkinson disease (PD). We set out to identify a polymorphism in the 24-kDa subunit gene (NDUFV2) in patients with PD and determine whether genetic polymorphism of this gene is associated with a higher risk of PD. The subjects comprised 126 patients with PD, and the control group comprised 113 unrelated individuals without neurodegenerative disorders. A novel polymorphism (Ala29Val) in the mitochondrial targeting sequence of NDUFV2 was found in patients with PD. The distribution of the three genotypes was significantly different between the two groups (χ

= 0.0099 < 0.01). The risk of developing PD associated with homozygosity for this mutation was calculated as 2.40 (95% CI: 1.18–4.88). NDUFV2 constitutes one genetic risk factor for PD, and the mutation may well be a cause of complex I deficiency in this disease.</ce:simple-para>
