title: [Association study between NPY and YWHAH gene polymorphisms and schizophrenia].
abstract: A case-control study was carried out on a sample of 583 cases vs. 372 controls in the Chinese Han population, investigating several published polymorphisms in the YWHAH and NPY genes, which reported to be associated with schizophrenia. The polymorphism -134 (GCCTGCA)2-4, in the YWHAH was not analyzed for the failure of amplification, and the polymorphism T1128C in the NPY is not existent in the samples. The analysis was then emphasized on the variants -485C > T(NPY) and G753A(YWHAH). However, no significant differences of allele frequencies (with P values of 0.696 and 0.743, OR values of 1.041 and 0.962 respectively) or genotype frequencies (with P value of 0.45 and 0.75, chi2 = 1.51 and 0.58 respectively) among the matched groups were found. No sex-dependent effect was found either. Also,the analysis of the relative risk between the genotypes of the two genes indicates that the two genes could not cooperate with each other to add the risk of disease (P > 0.05). The results suggest that the polymorphisms - 485C > T (NPY) and G753A (YWHAH) are unlikely to be linked with genetic susceptibility to schizophrenia in the Chinese Han population.
