Transmission disequilibrium test of polymorphisms of serotonin transporter gene and schizophrenia based on family trios / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To investigate the relationship between two polymorphisms (Intronic VNTR and 5-HTTLPR) of the serotonin transporter gene and schizophrenia.</p><p><b>METHODS</b>A set of 314 schizophrenic trio samples collected from Shanghai, Xi'an and Jilin regions of China independently was subjected to analysis of the polymorphisms by transmission/disequilibrium test(TDT).</p><p><b>RESULTS</b>No significantly preferential transmission of any allele was detected from both polymorphisms investigated.</p><p><b>CONCLUSION</b>The results suggest that the serotonin transporter gene is unlikely to have a major contribution to susceptibility to schizophrenia in Han Chinese population.</p>
