single nucleotide polymorphism (SNP); single nucleotide variation (SNV)

Genetics

• variability of a single nucleotide within a gene in a population
• the human genome contains about 10 million single nucleotide polymorphisms (SNPs)
• the HapMap is a mapping of such SNPs

Notes

• morbidmap is a compilation of diseases associated with gene loci
  • SNP data are associated with these gene loci (see morbidmap)

More general terms

• genetic polymorphism
