Abstract:
Objective To explore the correlation between 4 tag single nucleotide polymorphisms （Tag SNP） sites （rs7721799, rs32897, rs7718461, rs10062367） of corticotropin releasing hormone binding protein （CRHBP） and schizophrenia and aggressive behavior in the Yunnan Han population. Methods Case-control correlation analysis was used to establish a complex amplification system. Improved multiplex ligase detection reaction （iMLDR） technology was used to detect the genotypes of 4 SNP sites of CRHBP gene of 163 Han schizophrenic patients （including 81 patients with aggressive behavior, 82 patients without aggressive behavior） and 345 healthy Han individuals, which were analyzed statistically by SPSS 19.0, Haploview 4.2 and PHASE 2.1 software. Results There was no correlation between the 3 SNP sites of CRHBP gene and the onset of schizophrenia except for the rs7718461 site （P>0.05）. The relative risk of aggressive behavior of patients carrying GG or GA genotype at rs7718461 site were 4.903 times higher than those carrying AA genotype （P<0.05）. Conclusion The CRHBP gene may not be associated with the occurrence of schizophrenia in Yunnan Han population, but AA genotype of rs7718461 may reduce the risk of aggressive behavior in schizophrenia patients.
