摘要 目的探讨cAMP信号转导通路关联基因标签单核苷酸多态性(tagSNP)与反复发作抑郁症患者的关联。方法收集1030例反复发作抑郁症患者(病例组)和851名汉族健康对照者(对照组),采用Sequenom技术检测cAMP信号转导通路关联基因tagSNP位点的基因型和等位基因频率,同时比较其在病例组与对照组之间的分布差异。结果在病例组和对照组中,ADCY7基因rs1064448和HTR2A基因rs17068986的基因型和等位基因频率在两组间的差异有统计学意义(P〈0.05);ADCY9基因rs2531995、BDNF基因rs10835210、rs7124442、CREB1基因rs4675690、rs2551645、HTR2A基因rs3125基因型(492:423:112,356:401:91;538:392:94,414:371:61;24:165:838,3:150:694;219:468:337,139:418:237;153:481:393,115:446:286;53:286:688,25:296:524)在两组间的分布差异均有统计学意义(P〈0.05);余下的基因位点基因型和等位基因频率在两组间的差异均无统计学意义(P〉0.05)。在性别分析中,男性ADCY7基因rs106448和CREB1基因rs2551645的基因型和等位基因频率在两组间的差异有统计学意义(P〈0.05);男性ADCY9基因rs2531995、BDNF基因rs10835210、CREB1基因rs4675690、HTR2A基因rs3125的基因型(195:177:49,193:423:41;221:158:42,237:201:28;83:188:148,85:237:122;24:113:284,10:176:281)在两组间的差异有统计学意义(P〈0.05);其余tagSNPs在男性病例对照组中的基因型和等位基因分布差异无统计学意义(P〉0.05)。女性ADCY7基因rs1064448和HTR2A基因rs17068986的基因型和等位基因频率在两组问的差异有统计学意义(P〈0.05);女性BDNF基因rs7124442和CREB1基因rs4675690基因型(16:94:497,1:73:308;136:280:189,54:181:115)在两组问的差异有统计学意义(P〈0.05);女性ADCY9基因rs2531995等位基因(840:372,493:267)在两组间的差异有统计学意义(P〈0.05);其余tagSNPs在女性病例对照组中的基因型和等位基因分布差异均无统计学意义(P〉0.05)。结论ADCY7rs1064448及CREB1rs4675690可能和中国汉族人群反复发作抑郁症有关。 Objective To investigate the possible role of tag single nucleotide polymorphisms in cAMP signaling pathway in patients with recurrent major depressive disorder in Chinese HaM population. Methods 1 030 patients with recurrent major depressive disorder according to the DSM-Ⅳ criteria were recruited as case group and 851 age- and gender- matched healthy volunteers were recruited as control group. The sequenom mass spectrometry method was adopted to explore the genotype and allele frequency distributions of tag single nucleotide polymorphisms of cAMP signaling pathway in the two groups. Results The differences of genotype and allele frequencies of the ADCY7 gene loci rs1064448 and HTR2A gene loci rs17068986 were significant between case group and control group (P〈0.05).The difference of the genotype frequencies(492 : 423 : 112,356 : 401 : 91;538 : 392 : 94,414 : 371 : 61;24 : 165 : 838,3 : 150 :694;219 : 468 : 337,139 : 418 : 237;153 : 481 : 393,115 : 446 : 286;53 : 286 : 688,25 : 296 : 524)of the ADCY9 gene loci rs2531995, BDNF gene loci rs10835210, rs7124442, CREB1 gene loci 4675690, rs2551645 and the HTR2A gene loci rs3125 were significant in case-control group(P〈0.05) ;while the rest tagSNPs had no statistical difference in genotype and allele distribution frequencies in case-control group(P〉 0.05) .In gender-specific analyses, the differences of the genotype and allele frequencies of the ADCY7 gene loci rs106448 and CREBI gene loci rs2551645 were significant in male case-control group (P〈 0. 05 ) ; the differences of the genotype(195 : 177 : 49,193 : 423 : 41;221 : 158 : 42,237 : 201 : 28;83 : 188 : 148, 85:237 : 122; 24 : 113 : 284, 10 : 176 : 281)of the ADCY9 gene loci rs2531995,BDNF gene loci rs10835210, CREB1 gene loci rs4675690,and HTR2A gene loci rs3125 were significant in male case-control group(P〈0.05) ;while the rest tagSNPs had no statistical difference in genotype and allele distribution frequencies in male case-control group(P〉0.05).The differences of the genotype and allele frequencies of the ADCY7 gene loci rs1064448 and HTR2A gene loci rs17068986 were significant in female case-control group (P〈0.05). The differences of the genotype( 16 : 94 : 497,1 : 73 : 308;136 : 280 : 189,54 : 181 : 115)of the BDNF gene loci rs7124442 and CREB1 gene loci rs4675690 were significant in female case-control group(P〈0.05). The differences of the allele frequencies(840:372,493:267) of the ADCY9 gene loci rs2531995 were significant in female case-control group(P〈0.05),while the rest tagSNPs had no statistical difference in genotype and allele distribution frequencies in female case-control group (P〉 0. 05 ) . Conelusion The ADCY7 gene loci rs1064448 and CREB1 gene loci rs4675690 are associated with recurrent major depressive disorder in Chinese Han population.
