Furthermore, haplotype analysis revealed that GCT, ACT, and GCC haplotypes containing rs4795896, rs17735961 and rs17809012 were significantly associated with schizophrenia (p = 0.0044, p < 0.0001, and p < 0.0001, respectively).
Gene expression disturbances in the brain of subjects with schizophrenia show complex, region-specific changes with consistently replicated and potentially interdependent induction of serpin peptidase inhibitor, clade A member 3 (SERPINA3) and interferon inducible transmembrane protein (IFITM) family transcripts in the prefrontal cortex.
Further analysis of the haplotype rs1006737-rs4765905-rs882194 in CACNA1C showed significant associations with schizophrenia (corrected global p<0.005), and two haplotypes (ACC and ACT) in the block were significantly increased in the patients.
