Reference	Tested Markers	Statistical Values/Author Comments	Result Category	Comment on Study
Papadimitriou, G. N., 1998	Other variant: GABRA5_(CA)n	The distribution of allelic frequencies of the GABRA5 locus differed significantly between BP patients and controls with the 282-bp allele found to be associated with BP affective disorder.	Positive	Comment on Study
Duffy, A.,2000	Other variant: GABRA5_GDB162554	In conclusion, our study does not support the hypothesis that genes coding for CRH or PENK contribute to the genetic susceptibility to bipolar disorder.	Positive	Comment on Study
Otani, K.,2005(a)	SNP: rs140681, rs140683, rs6606854 Haplotype: rs140681 - rs140683(A-A), rs140681 - rs140683(A-T), rs140681 - rs140683(G-A), rs140681 - rs140683(G-T) Other variant: GABRA5_+11547_(CA)n	These results suggest that the GABRA5 gene may confer susceptibility to bipolar I disorder.	Positive	Comment on Study
Yosifova, A.,2009	SNP: rs140681	Significant association of SNP in this gene with BD in our population was observed.	Positive	Comment on Study
Oruc, L., 1997 ( c)	Other variant: GABRA5_3'UTR_1-8 allele	ln the view of thesc observations, our data could be explained by assuming that allele 4 of the GABRA5 gene polymorphism confers a higher risk to UPR major depression but not necessarily to BPI disorder which combines major depression with manic episodes.	Positive	Comment on Study
Craddock, N., 2010	SNP: rs17561681	set-based analysis for gene-wide P-value = 0.0024. gene-wide levels of statistical significance in RDC SABP samples, but not other subsets of samples.	Positive	Comment on Study
