Correlation between mRNA expression levels

	SNCA (probe 29 939)	CTSD (probe 52 556)	GAK exon 26 (probe 155 700)	GAK exon 28 (probe 397 150)
SNCA		0.10 (0.58)	0.15 (0.42)	−0.13 (0.47)
CTSD	0.28 (0.14)		0.45 (0.009)	0.18 (0.31)
GAK exon 26 (probe 155 700)	0.18 (0.34)	0.50 (0.006)		0.79 (<0.0001)
GAK exon 28 (probe 397 150)	−0.27 (0.16)	0.02 (0.93)	0.58 (0.001)

Correlations were computed separately for PD cases (above diagonal) and controls (below diagonal). P-values are indicated in parentheses.
