A single nucleotide polymorphism, or SNP, is a variation in a single nucleotide base that distinguishes one allele from another. SNPs are the most common type of genetic variation and can occur throughout the genome. Variations in a single base can result in different amino acids being incorporated into a protein or affect how a gene is regulated. SNPs have been linked to many human diseases and are important markers for genetic studies.
