Several lines of evidence suggest an involvement of the noradrenergic neurotransmitter system in the pathogenesis of bipolar affective disorder (BPAD). Three genes for alpha-adrenergic receptors (ADRA) are located in chromosomal regions that showed evidence for linkage: The alpha(1c)-adrenergic (ADRA-1C) receptor gene on 8p21, the alpha(2a)-adrenergic (ADRA-2A) receptor gene on 10q25, and the alpha(2c)-adrenergic (ADRA-2C) receptor on 4p16. In a BPAD sample of 120 parent-offspring triads, we genotyped a 492 Cys/Arg variant in exon 2 of the ADRA-1C gene, a -1291 G/C variant in the 5'UTR of the ADRA-2A gene, and a STR marker (adra2c1) in the 5'UTR of the ADRA-2C gene. Using the Transmission Disequilibrium Test (TDT), no significant differences in transmissions were observed for any of the three ADRA genes.
多条证据表明去甲肾上腺素能神经递质系统参与双相情感障碍(BPAD)的发病机制。α-肾上腺素能受体(ADRA)的三个基因位于显示有连锁证据的染色体区域:位于8p21的α(1c)-肾上腺素能(ADRA-1C)受体基因、位于10q25的α(2a)-肾上腺素能(ADRA-2A)受体基因以及位于4p16的α(2c)-肾上腺素能(ADRA-2C)受体。在一个由120个亲子三联体组成的BPAD样本中,我们对ADRA-1C基因外显子2中的一个492 Cys/Arg变体、ADRA-2A基因5'UTR中的一个-1291 G/C变体以及ADRA-2C基因5'UTR中的一个STR标记(adra2c1)进行了基因分型。使用传递不平衡检验(TDT),未观察到三个ADRA基因中的任何一个在传递上有显著差异。
