Background: Parkinson's disease (PD) is a multifaceted illness affecting ~ 0.3% of the world population. The genetic complexity of PD has not been, fully elucidated. Several studies suggest that mitochondrial DNA variants are associated with PD. Objective: Here, we have explored the possibility of genetic association between mitochondrial haplogroups as well as three independent SNPs with PD in a representative east Indian population. Methods and Material: The Asian mtDNA haplogroups: M, N, R, B, D, M7, and 3 other SNPs: 4336 T/C, 9055 G/A, 13708 G/A were genotyped in 100 sporadic PD patients and 100 matched controls via conventional PCR-RFLP-sequencing approach. Results: The distribution of mtDNA haplogroups, as well as 3 single polymorphisms, did not show any significant differences (P > 0.05) between patients and controls. Conclusion: This is the first of its kind of study from India that suggests no association of selected mitochondrial DNA variations with PD. © 2021 Wolters Kluwer Medknow Publications.
