Abstract
In a previous study, we confirmed that copy number variants (CNVs) within the VIPR2 gene in Han Chinese individuals exhibit an increased risk of schizophrenia (SCZ). Herein, we further analyzed the association of eight tagged single nucleotide polymorphisms (tagSNPs) from the HapMap database with SCZ susceptibility. However, we found no significant positive signals in overall association and haplotypes analyses. Interestingly, significant SNP-SNP interaction signals associated with the risk of SCZ were observed using Multifactor Dimensionality Reduction (MDR) analysis. Furthermore, the 'CC' genotype of the VIPR2 gene was nominally associated with an increased risk of SCZ in male patients.
