侧翼区(flanking region)
根据维基定义：The 5' flanking region is a region of DNA that is adjacent to the 5' end of the gene. The 5' flanking region contains the promoter, and may contain enhancers or other protein binding sites. It is the region of DNA that is not transcribed into RNA.
以5'侧翼区为例，侧翼区是指与基因5’末端毗连的DNA区域，这些区域通常包含启动子、增强子或者其他蛋白质结合位点，这部分的区域不能被转录为RNA。
侧翼区单核苷酸多态性(Flanking SNPs)
根据维基定义：Flanking SNPs are Single nucleotide polymorphisms (SNP) that appear in the flanking region. Polymorphisms in this region can lead to changes in the regulation of transcription.
是指出现在侧翼区的SNP,在这个区域的SNP可能导致转录调控发生改变。
