A single nucleotide polymorphism (SNP) is a potential genetic mutation that occurs in a single spot in the human genome.[1] A single spot in the human genome is represented physically by a particular nucleotide base-pair in the DNA, such as cytosine-guanine or adenine-thymine. For example, 60% of the general population may have a cytosine-guanine base pair at a particular location in their DNA, but 40% of the population may have a adenine-thymine base pair at that location instead. SNP's are often represented by an "rs" number, such as "rs53576".[2]
