Associations between specific SNPs and either type of TD in the Dutch and Siberian schizophrenic populations.

Receptor	SNP	Dutch population	Siberian schizophrenic population
		TD (B, P value)	TD (OR (95% CI), P value)	TD expression level: sum of scores for 1–7 signs (P valuea)
GRIN2B	rs2192970	X	OR = 1.93 (1.22–3.06), P = 0.005411	X
GRIN2A	rs1345423	B = −0.13, P = 0.0421	OR = 0.42 (0.20–0.89), P = 0.015210	P = 0.014524
	rs7192557	B = 0.22, P = 0.0159	X	X
	rs1650420	B = 0.16, P = 0.0193	X	X
	rs11644461	B = −0.13, P = 0.0385	X	X
DRD3	rs324035	X	X	P = 0.03211
	rs167770	X	X	P = 0.02197

OR: odds ratio; 95% CI: 95% confidence interval.

Bold italics are statistically significant in both populations.

B = regression coefficient, P = chance, sum of scores = scores of AIMS scale.
