Reference	Tested Markers	Statistical Values/Author Comments	Result Category	Comment on Study
Smith, E. N.,2009	SNP: rs2769605	For the AA sample, SNPs with the strongest statistical evidence for association included rs2111504 in DPY19L3 at 19q13.11 (P=1.5E-06) and rs2769605 in NTRK2 at 9q21.33 (P=4.5E-05).	Trend	Comment on Study
Soronen, P.,2011	SNP: rs3654	No significant association of this gene was observed in BD.	Negative	Comment on Study
Wang, Z., 2013	SNP: rs2769605, rs1565445, rs1387923	However, no significant association between NTRK2 gene polymorphisms and BP I susceptibility was observed after correcting for multiple comparisons. The results suggest that the NTRK2 gene polymorphism likely plays an essential role in treatment response to mood stabilizers in Han Chinese BP I patients.	Positive	Comment on Study
