From Wikipedia, the free encyclopedia

Paragraphs being worked on:

Single-nucleotide polymorphisms may fall within coding sequences of genes, non-coding regions of genes, or in the intergenic regions(regions between genes). SNPs within a coding sequence do not necessarily change the amino acid sequence of the protein that is produced, due to degeneracy of the genetic code.[1] - complete and added to live article

SNPs in the coding region are of two types: synonymous SNPs and non-synonymous SNPs. Synonymous SNPs do not affect the protein sequence, while non-synonymous SNPs change the amino acid sequence of protein.[2] -complete and added to live article


More than 600 million SNPs have been identified across the human genome within the world's population.[3]
