A single-nucleotide polymorphism, often abbreviated to SNP (/ËsnÉªp/; plural /ËsnÉªps/), is a variation in a single nucleotide that occurs at a specific position in the genome, where each variation is present to some appreciable degree within a population (e.g. > 1%).
1 Genetic variation is a result of subtle differences in our DNA. 2  Single nucleotide polymorphisms (SNPs, pronounced âsnipsâ) are the most common type of genetic variation amongst people. 3  Each single nucleotide polymorphism represents a difference in a single DNA base, A, C, G or T, in a personâs DNA.
