Comparative genome hybridization array analysis for sporadic Parkinson's disease

Int J Neurosci. 2008 Sep;118(9):1331-45. doi: 10.1080/00207450802174522.


Parkinson disease (PD) is a common neurodegenerative disorder, characterized by the loss of midbrain dopamine neurons and Lewy body inclusions. We investigated array CGH to analyze gain or loss of genetic material from 30 patients with PD. We identified the frequent copy number variations in PD; gains in 1p21.1, 4p15.31, 5p15.33, 6q24.1, 7q35, 8q24.3, 10q26.3, 11p15.5-15.4, 12q21.2, 16p13.3, 18q12.3 and 22q13.31, and losses in 1p36.33, and 5q13.2. These findings enable a better description of genetic variations in PD, and could provide a foundation for understanding the critical regions of the genome that may be involved in the development of PD.
