Abstract

MtDNA haplogroups J and K have been associated with a decreased risk of developing Parkinson's disease (PD). To confirm this finding, we compared the distribution of mtDNA haplogroups J and K in a large sample of Australian patients with PD (n = 890) to population-based controls (n = 3,491). We assigned subjects to haplogroups J or K using standard PCR/ RFLP techniques. Of the 890 subjects with PD, 10.6% were haplogroup J (95% CI 8.6-12.8, n = 94) and 7.1% were haplogroup K (95% CI 5.5-8.9, n = 63). In our controls, 10.2% belonged to haplogroup J (95% CI 9.2-11.2, n = 356), and 7.8% were in haplogroup K (95% CI 6.9-8.7, n = 272). There was no significant difference in the prevalence of mtDNA haplogroup J or K in PD patients compared to population-based controls. Our findings indicate that mtDNA haplogroups J and K are not associated with a lower risk of PD.
