rs11178997 Hardy–Weinberg equilibrium test between ODD and control group

Group	Genotype
	AA	AT	TT	Total	χ2	χ2*	P
ODD group						1.292	0.256
Observation (O)	6	33	84	123
Expectation (E)	4.116*	36.768	82.116	123
Control group						0.052	0.820
Observation (O)	4	39	109	152
Expectation (E)	3.633*	39.734	108.63	152

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