Why don’t silent mutations cause problems? What makes them silent?

WebSNPs may change the encoded amino acids (nonsynonymous) or can be silent (synonymous) or simply occur in the noncoding regions. They may influence promoter activity (gene expression), messenger RNA (mRNA) conformation (stability), and subcellular localization of mRNAs and/or proteins and hence may produce disease. WebThe result is a sandy-colored mouse. The mutated version of the Mclr gene, however, triggers melanocytes to increase the production of eumelanin, resulting in the dark coat-color phenotype.
