Fan, J., 2010		For gene-based test, P-value = 0.063 in STEP1. non-significant in any samples.	Negative	Comment on Study
Mansour, H. A.,2009		Gene-based tests:X<sup>2</sup>=4.971, P-value = 0.304 in recessive model, X<sup>2</sup>=3.233, P-value = 0.623 in dominant model, X<sup>2</sup>=2.629, P-value = 0.643 in additive model in BPI.

Monteleone, P.,2010	SNP: rs1049353	A case-control study using the missense polymorphism, 2316A>G (Ile772Met), and the tetranucleotide repeat (TTTA)n showed no significant association with mood disorders in Japanese samples.	Negative	Comment on Study
Byrne, E. M., 2014		P-value=0.11. When ranking genes based on the most significant SNP, the strongest signal was rs9353523 in the CNR1 gene (P=0.001).	Negative	Comment on Study
