GADL1 and bipolar disorder: Among healthy controls, rs17026688 T and non-T carriers showed significant differences on the secretion of GADL1, taurine, and GABA in the plasma in this study, suggesting that the SNP rs17026688 itself had influence on the plasma levels of GADL1, taurine, and GABA secretions, which might not be related with bipolar disorder or lithium drug use.
