Changes in the relative mRNA levels of VCP, SNCA in the peripheral blood of patients.

Genes	Treated patients with PD	Untreated patients with PD	Neurological control	Patients with “predicted” PD
SNCA	0.18a	0.25	0.14	0.54
	0.05–0.29b	0.06–1.22	0.10–0.86	0.48–0.72
	0.001c	0.004	0.004	0.03
VCP	1.11	0.43	0,97	0.54
	0.37–2.06	0.19–0.95	0.43–2.25	0.25–0.64
	0.61	0.0003	0.79	0.01

^aMedian; ^b25–75 percentiles; ^cp-value. The data in bold are statistically significant (p < 0.05). The levels of the transcripts studied in the control group were taken as 1. The data are presented as a fold change (N-fold) in expression compared with the control.
