摘要
目的:探讨SLC5A7( Solute carrier family 5,member 7)基因rs1013940位点单核苷酸多态性与中国汉族人群Tourrette综合征( Tourette syndrome,TS)发病的关联性。方法采用实时荧光定量PCR技术对来自中国汉族人群的401个TS核心家系SLC5A7基因rs1013940位点多态性进行检测,传递不平衡检验( transmission dsequilibrium test,TDT)和单倍体相对风险分析( haplotype relative risk,HRR)方法分析该多态性位点的遗传分布与TS的关系,应用基于单倍型的单倍型相对风险分析(haplotype-based HRR,HHRR)进行验证。结果 TDT和HRR结果均表明,SLC5A7基因rs1013940位点与TS之间不存在明显关联( TDT:χ2=0.268, P=0.657, OR=0.728,95%CI =0.366~1.451;HRR:χ2=0.111, P=0.739, OR=0.959,95%CI =0.762~1.466)。 HHRR结果同样表明,两者之间差异无统计学意义( HHRR:χ2=0.276, P=0.599, OR=1.082,95%CI =0.806~1.453)。结论 SLC5A7基因rs1013940位点基因多态性与中国汉族人群TS的发病无明显关联,但仍需在不同种族中进行验证。
Objective To investigate the association between rs1013940 in SLC5A7 and Tourette Syndrome ( TS) in Chinese Han population.Methods Polymorphism was genotyped in 401 TS nuclear fam-ilies trios from china by real-time fluorescent quantitive PCR.Transmission disequilibrium test ( TDT) and Haplotype relative risk ( HRR ) were used to analyze the association between the genetic distrbution of rs1013940 and TS and the results were verified by haplotype-based haplotype relative risk( HHRR) .Results No transmission disequilibrium was found between rs1013940 in SLC5A7 and TS by TDT and HRR( TDT:χ2=0.268, P=0.657, OR=0.728,95%CI=0.366-1.451;HRR:χ2=0.111, P=0.739, OR=0.959,95%CI=0.762-1.466) .HHRR also indicated the same result ( HHRR:χ2=0.276, P=0.599, OR=1.082,95%CI=0.806-1.453) .Conclusion The result reveals that there is no significant association between rs1013940 in SLC5A7 and TS in Chinese Han population.However,the results need to be further validated in different populations.
