Reference	Tested Markers	Statistical Values/Author Comments	Result Category	Comment on Study
Stopkova, P., 2004 (b)	Other variant: SYNJ1_intron12_IVS12+15delT,+17delT	In conclusion, although we did not replicate the original finding, the role of SYNJ1 in the pathogenesis of bipolar disorder cannot be ruled out and further investigation is warranted.	Negative	Comment on Study
Saito, T.,2001	Other variant: SYNJ1_IVS12+15delT,+17delT, SYNJ1_IVS28-7G/T, SYNJ1_IVS29+14C/T, SYNJ1_K295R	We failed to unequivocally identify a specific SYNJ1 allele that could be responsible for putative chromosome 21q22-linked BPD.	Negative	Comment on Study
