Reference	Tested Markers	Statistical Values/Author Comments	Result Category	Comment on Study
Del-Favero, J.,2002	Other variant: TCF4_CTG18.1	Expanded alleles at the CTG18.1 locus cannot be excluded as a vulnerability factor for BP disorder.	Positive	Comment on Study
McInnis, M. G.,2000	Other variant: TCF4_CTG18.1	There are no data to implicate the CTG18.1 repeat within the SEF2-1b gene, and the current study indicates that CTG18.1 is unlikely to make a substantial contribution to vulnerability to these disorders, though a minor contribution can not be ruled out.	Negative	Comment on Study
Williams, H. J.,2011	SNP: rs9960767	Using data sets entirely independent of their original discoveries, we observed no significant evidence (P < 0.05) that the TCF4 region is associated with BD.	Negative	Comment on Study
Steinberg, S.,2012	SNP: rs4309482, rs9960767	No significant association was observed.	Negative	Comment on Study
Meira-Lima, I. V.,2001	Other variant: TCF4_CAG/CTG repeat	Our data do not support the hypothesis that variation at the polymorphic CAG/CTG repeat loci SEF2-1b influence susceptibility to BPAD in our sample.	Negative	Comment on Study
Jin, D. K.,2001	Other variant: TCF4_CTG18.1	A longer CAG repeat alleles of KCNN3 or CTG 18.1 may not be a risk factor for BPAD in Korean population.	Negative	Comment on Study
