Abstract
Objective To explore whether the polymorphism of human frizzled 3 (rs2241802 ,rs2323019,rs352203) is associated with schizophrenia in Yunnan Han population. Methods PCR-RELP was used to detect the polymorphism of human frizzled 3 (rs2241802 ,rs2323019, rs352203 ) in 153 patients and 100 controls. All patients were evaluated with positive and negative symptom scale(PANSS). Following a linkage disequilibrium test in the 3 loci ,association analysis was carried out between the polymorphism, including haplotype,and schizophrenia in all samples. Results No significant difference of genotype and allele frequency of the 3 loci were observed in 2 groups. There was no difference in genotype and allele frequency of rs2241802 ,rs2323019,rs352203 in Han samples (P>0.05) . The polymorphisms of the 3 loci had been observed no difference in case-sibling control study of normal group. A-A-C haplotype and G-A-C haplotype were observed with a higher frequency in both samples (P<0.05). There was no difference in patients and controls in PANSS scores (P > 0.05 ). Conclusions There is no association between polymorphisms of human frizzled 3 ( rs2241802, rs2323019, rs352203 ) and schizophrenia in Han. A-A-C and G-A-C haplotype might possibly associate with schizophrenia in Yunnan Han population.
