Reference	Tested Markers	Statistical Values/Author Comments	Result Category	Comment on Study
Lee, S. Y., 2012	Other variant: ALDH2_12 allele	ALDH211: P-value = 0.002, OR(95% CI)=4.48(1.76-11.40) in BP-I, P-value = 0.425, OR(95% CI)=1.34(0.66-2.73) in BP-II. The regression showed a significant association of the ALDH2 with BP-I only.	Positive	Comment on Study
Lee, S. Y.,2010	Haplotype: ALDH2_1/2 - rs1800497((ALDH2_11)-(DRD2 Taq-I A1/A2)), ALDH2_1/2 - rs1800497((ALDH2_11)-(DRD2Taq-I A1/A1)) Other variant: ALDH2_1/2	Our findings may provide initial evidence that the ALDH2 and DRD2/ANKK1 genes interact in specific subtypes of bipolar disorders. Our findings also suggest a unique genetic distinction between bipolar I and bipolar II disorders.	Positive	Comment on Study
Wang, Y. S., 2013		a significant interaction of the DRD2 Taq-I A1/A1 and the ALDH211 genotypes in BP-II without AD was revealed compared with normal controls	Positive	Comment on Study
