rs1386494 Hardy–Weinberg equilibrium test between ODD and control group

Group	Genotype
	AA	AG	GG	Total	χ2	χ2*	P
ODD group						0.138	0.711
Observation (O)	0	8	116	124
Expectation (E)	0.129*	7.742	116.129	124
Control group						0.856	0.355
Observation (O)	0	21	128	149
Expectation (E)	0.740*	19.520	128.740	149

df = 1* when E is little than 5, we use Yates corrected Chi squared test, χ^2*
