Analysis of the genotyping data extracted from our hospital database revealed that rs334558 exhibited exclusive association with MDD in female patients (P=0.015).Our findings suggest that GSK3β rs334558 polymorphisms might be a potential risk for MDD, and females with GSK3β rs334558 polymorphisms might have higher penetrance of MDD.
Under a dominant model, we observed a potential association between the GSK3B rs6782799 and MDD (P=0.07), a significant three-way interaction among BDNF rs6265, GSK3B rs6782799, and negative life events (corrected P-value, 0.011-0.012; cross-validation consistency, 7; prediction error, 0.4349).
Further gene-gene interaction analyses showed a significant effect of a two-locus BDNF/GSK3B interaction with MDD (GSK3B rs6782799 and BDNF rs7124442) (corrected P = 0.011), and also for a three-locus interaction (GSK3B rs6782799, BDNF rs6265 and BDNF rs7124442) (corrected P = 0.019).
To investigate whether common genetic variants in the GSK3B gene are associated with MDD and the therapeutic response to antidepressants, four polymorphisms (rs334558 (-50 T>C), rs13321783 (IVS7+9227 A>G), rs2319398 (IVS7+11660 G>T) and rs6808874 (IVS11+4251 T>A)) of the GSK3B gene were genotyped in 230 Chinese MDD patients and 415 controls.
We found rs334535 (Pallele=2.79E-03, Pgenotype=5.00E-03, OR=1.429) and rs2199503 (Pallele=0.020, Pgenotype= 0.040, OR=1.157) showed association with major depressive disorder before Bonferroni correction. rs6771023 (adjusted Pallele=1.64E-03, adjusted Pgenotype=6.00E-03, OR=0.701) and rs2199503 (adjusted Pallele=0.001, adjusted Pgenotype=0.002, OR=1.251) showed significant association with schizophrenia after Bonferroni correction. rs2199503 (adjusted Pallele=1.70E-03, adjusted Pgenotype=0.006, OR=1.208) remained to be significant in the combined cases of major depressive disorder and schizophrenia after Bonferroni correction.

Our results suggest the GSK3β genotypic effect of rs6438552 and its interaction with disease status may contribute to the altered topological organization of resting state functional brain networks in MDD patients.
