RESUMO
<p><b>OBJECTIVE</b>To study the association between the single nucleotide polymorphisms (SNPs) in FXYD6 gene and schizophrenia in a family-trios population.</p><p><b>METHODS</b>Six SNPs (rs10790212, rs11544201, rs555577, rs1815774, rs4938446 and rs497768) in the FXYD6 gene were genotyped by allele-specific PCR method in 101 nuclear families, and transmission disequilibrium test (TDT) was performed.</p><p><b>RESULTS</b>SNPs rs10790212 and rs11544201 showed significant association with schizophrenia (P<0.05). Furthermore, significant association of schizophrenia with the haplotype rs10790212-rs11544201 was found (P<0.05).</p><p><b>CONCLUSION</b>FXYD6 gene might play an important role in schizophrenia susceptibility and functional analysis of FXYD6 are needed.</p>
