Objectives

Heat shock proteins (HSPs) are a promising candidate gene in schizophrenia as they are believed to play a protective role in the central nervous system. An alteration in the titers of antibodies to the HSPs in schizophrenia patients has been suggested. Association between the three polymorphisms of HSP70-1 (HSPA1A), HSP70-hom (HSPA1L) and HSP70-2 (HSPA1B) and schizophrenia has been reported. Therefore, this study investigated the association between an enlarged set of SNPs at HSP70 gene and schizophrenia.

Methods

Two hundred and ninety-four patients with schizophrenia and 287 controls were enrolled in the study. Genotypings of 5 SNPs of HSP70 were performed using pyrosequencing method. Haploview 3.2 was used to generate a linkage disequilibrium map and to test for Hardy-Weinberg equilibrium. Single locus and haplotype-based associations were tested. Tests for associations using and multi-marker haplotypes were performed by using a COCAPHASE v2.403. Association of SNP markers and clinical variables were analyzed by analysis of variance.

Results

Significant association was detected at rs2075799 (allele A, X2 = 8.03, df = 1, P = 0.0046), but not at rs2227956 (P = 0.28), rs1043618 (P = 0.88), rs562047 (P = 0.47) or rs539689 (P = 0.32). In fact, the rs2075799*G/A genotype was more represented in patients with schizophrenia than in controls (X2 = 8.23, df= 1, P = 0.0041). Haplotype based associations were also detected (global P value 0.000003); the T-A-C-C-G haplotype was more prevalent among the patients (odds ratio, OR 5.95). Sliding windows analysis revealed a major contribution from rs2227956 and rs2075799 (global-P value 0.0075), with T-A haplotype significantly associated with schizophrenia. There was no evidence of an association between the clinical variables and schizophrenia across the genotypes.

Conclusion

Our results raise the possibility that HSP70 gene (i.e., haplotypes of rs2075799) might be implicated in the development of schizophrenia, although limited by rare haplotypic association with the disease. Hence further studies from different ethnics should be performed to confirm these results."xsd:string
