The present study investigated the possible association of the KPNA3 locus in the 13q14 region with schizophrenia. We detected 7 single nucleotide polymorphisms (SNPs) on 13q14, one (rs6313) present at the HTR2A locus and the other 6 at the KPNA3 locus, among 124 British family trios consisting of mother, father and affected offspring with schizophrenia. The transmission disequilibrium test (TDT) showed allelic association for rs3736830 (χ2 = 8.66, P = 0.003), rs2181185 (χ2 = 3.86, P = 0.049) and rs626716 (χ2 = 5.82, P = 0.016), but not for rs6313 (χ2 = 0.009, P = 0.926). The global P-value was 0.029 for 1000 permutations with the TDT. The 2-SNP haplotype analysis showed a disease association for the rs2273816-rs3736830 haplotypes (χ2 = 7.63, d.f. = 2, P = 0.022), the rs3736830-rs2181185 haplotypes (χ2 = 10.30, d.f. = 2, P = 0.006) and the rs2181185-rs3782929 haplotypes (χ2 = 9.26, d.f. = 2, P = 0.01). The global P-value was 0.034 for 1000 permutations with the 2-SNP haplotype analysis. The 6-SNP haplotype system also showed a weak association with the illness (χ2 = 15.62, d.f. = 8, P = 0.048), although the 1-d.f. test did not show the association for nine individual haplotypes when a P-value was corrected by the Bonferroni corrections. The present study suggests that the KPNA3 may contribute genetically to schizophrenia in a small effect size. © 2005 Elsevier Ireland Ltd and the Japan Neuroscience Society. All rights reserved.
