abstractText | 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 polymorph-ism 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 neurodegen-erative 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 (chi 2 = 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. |
