Disturbances in dopamine neurotransmission have been postulated to underlie schizophrenia. We report data from two independent studies of a BalI polymorphism in the dopamine D3 receptor gene in patients with schizophrenia. In both studies, more patients than controls were homozygous (p = 0.005, p = 0.008). When pooled data were analysed, this difference was highly significant (p = 0.0001) with a relative risk of schizophrenia in homozygotes of 2.61 (95% confidence intervals 1.60-4.26).
多巴胺神经传递紊乱被认为是精神分裂症的潜在病因。我们报告了两项关于精神分裂症患者多巴胺D3受体基因中一个BalI多态性的独立研究数据。在两项研究中,纯合子的患者均多于对照组(p = 0.005,p = 0.008)。对汇总数据进行分析时,这种差异具有高度显著性(p = 0.0001),纯合子患精神分裂症的相对风险为2.61(95%置信区间1.60 - 4.26)。
