- 单核苷酸多态性_百度百科
单核苷酸多态性(single nucleotide polymorphism,SNP)主要是指个体在基因组水平上由单个核苷酸变异所引起的DNA序列多态性,它们是基因组中最丰富的DNA分子标记类型。 1977年,随着DNA测序技术的诞生,科学家首次在分子水平上观察到单碱基替换导致的序列差异现象。
- Single Nucleotide Polymorphisms (SNPs)
A single nucleotide polymorphism (abbreviated SNP, pronounced snip) is a genomic variant at a single base position in the DNA Scientists study if and how SNPs in a genome influence health, disease, drug response and other traits
- Single-nucleotide polymorphism - Wikipedia
The development of tag SNP methodology has significantly enhanced the efficiency of genomic studies by exploiting patterns of linkage disequilibrium across the human genome

SNP是生物信息学常见的研究方向,在对群体遗传学、制药业、癌症及遗传性疾病甚至进化的研究文献里都经常能见到SNP的身影,目前人们已经通过研究SNP图谱更深刻的认识到了癌症、糖尿病、已经某些神经性疾病等疾病的…

大多数 SNP 是 双等位基因,这意味着在群体中我们只观察到两个可能的核苷酸变异出现在该位置(比如 A 和 G)。 个体有两条同源染色体 → 每个个体在这个 SNP 位点上会携带两个碱基。 因此基因型的可能性就是三种:AA、AG 和 GG。

单核苷酸多态性(SNP)位点已被用于全基因组关联研究(GWAS),例如,基因图谱中的高分辨率标记与疾病或正常的特征有关。 单核苷酸多态性(SNP)的知识将有助于了解药物的代谢动力学(PK)或药效动力学,即在不同的遗传变异个体中药物是如何发挥作用的。
- What are single nucleotide polymorphisms (SNPs)? - MedlinePlus
Each SNP represents a difference in a single DNA building block, called a nucleotide For example, a SNP may replace the nucleotide cytosine (C) with the nucleotide thymine (T) in a certain stretch of DNA SNPs occur normally throughout a person’s DNA
