Abstract:
Objective To examine the relationship of calcium channel, voltage-dependent, L type, alpha 1C subunit (CACNAIC) gene polymorphism with schizophrenia. Method A total of 118 patients with schizophrenia and 122 healthy volunteers were selected in succession. Denaturing high performance liquid chromatography (DHPLC) was used to analyze the genotypes of CACNAIC gene (rs10848683, rs2238032 and rs2299661). Medical record data of patients with schizophre?nia and the clinical manifestation of the patients (sensation and perception disorder, thought disorder, affective disorder and behavior disorder) were collected. The clinical phenotype databases of all patients were established. Result There were statistical differences for genotype and allele distribution of the rs2238032 and rs2299661 between patient group and control group (P<0.05). The TT genotype of rs2238032 (OR=0.394) and the CG genotype of rs2299661 (OR=0.326) associ?ated with the risk of schizophrenia. The genotype distribution of rs2238032 was related to the thought disorder, the emotion disorder and the PANSS score of schizophrenia patients (all P<0.05). The genotype distribution of rs2299661 was related to the perceptual disorders and PANSS score of schizophrenia patients (all P<0.05). Haplotype analysis showed that CTC (OR=1.811), CTG (OR=0.432) and TGC (OR=1.771) were significantly associated with schizophrenia (P<0.05). Conclu?sion The CACNA1C gene polymorphism is associated with schizophrenia and its clinical manifestations.
