请问 SNV(single nucleotide variants)和 SNP(single nucleotide polymorphism)有什么区别?在测序结果处理中遇到过,不明白什么区别,
网友回答
【答案】 SNP (single nucleotide polymorphism) vs.SNV (single nucleotide variant) As their name suggests,both are concerned with aberrations at a single nucleotide.However,a SNP is when an aberration is expected at the position for any member in the species – for example,a well characterized allele.A SNV on the other hand is when there is a variation at a position that hasn’t been well characterized – for example,when it is only seen in one individual.It is really all a question of frequency of occurrence.
大意是如果在一个物种中该单碱基变异的频率达到一定水平就叫SNP,而频率未知（比如仅仅在一个个体中发现）就叫SNV.
