由于多巴胺(DA)D2受体是神经阻滞剂治疗的靶点,并且已发现在精神分裂症中升高,因此检查了人DA D2受体基因在精神分裂症中可能的异常。此外,由于精神病中的D2受体与D1受体的偶联减少,因此选择D2的细胞质第三环进行脱氧核糖核酸(DNA)测序,因为该区域对于偶联G蛋白至关重要。该区域还包含外显子5,其以长形式D2表达,但不以短形式D2表达。在8例精神分裂症患者中,该区域的外显子序列(外显子4、5和6)正常,内含子-外显子连接处的序列正常。然而,外显子6包含三个DNA多态性碱基的变化,内含子4和5显示三个碱基缺失和两个多态性碱基的变化,没有一个会改变精神分裂症的D2受体蛋白。
Because dopamine (DA) D2 receptors are a target in neuroleptic therapy and have been found to be elevated in schizophrenia, the human DA D2 receptor gene was examined for possible abnormalities in schizophrenia. Moreover, since D2 receptors in psychosis have a reduced coupling to D1 receptors, the cytoplasmic third loop of D2 was chosen for deoxyribonucleic acid (DNA) sequencing, since this region is essential for coupling to G-proteins. This region also contains exon 5, which is expressed in the long form of D2, but not in the short form of D2. In eight schizophrenia cases, this region had normal exon sequences (exons 4, 5 and 6), and normal sequences at its intron-exon junctions. However, exon 6 contained three DNA polymorphic base changes, and introns 4 and 5 revealed three missing bases and two polymorphic base changes, none of which would be expected to alter the D2 receptor protein in schizophrenia.
