Synonymous single - nucleotide polymorphisms (SNPs) do not produce altered coding sequences, and therefore they are not expected to change the function of the protein in which they occur.

Soon after researchers began to sequence individual genomes 5 years ago, they realized that everyone's DNA seems to have major mutations that disable the protein for which the gene codes.
