摘要
Associations between schizophrenia and four candidate genes were tested among Indian patients with schizophrenia and their parents (DSM-IV criteria, n = 179 families). Polymorphisms within the genes encoding the serotonin 2A receptor (HT2A), tryptophan hydroxylase (TPH), catechol-O-methyl transferase (COMT) and dopamine transporter (DAT) were thus investigated. Two polymorphisms each were analyzed at HT2A and TPH, enabling haplotype-based analyses using the transmission disequilibrium test (TDT) for these genes. No significant associations were detected. Pooled analysis of samples like ours may be necessary to definitively exclude putative allelic associations at these loci.
