Hardy Weinberg equilibrium and LD variance for the three EAAT2 SNPs using pyrosequencing or SSCP

	Pyrosequencing	SSCP
	Hardy-Weinberg
for -168	p > 0.99	N/A
for -181	p = 0.0188	p = 0.4063
for -200	p = 0.0256	p = 0.3325
	Lewontin’s D’
-168 and -181	0.49	N/A
-168 and -200	1	N/A
-181 and -200	0.94	1
	r 2
-168 and -181	0	N/A
-168 and -200	0	N/A
-181 and -200	0.79	0.99

Lewontin’s D’ and r² both give ordinal measures of Linkage Disequilibrium (LD). Please note only one mutation was found at -168 making interpretation difficult for these associations.
