Point mutations have a variety of effects on the downstream protein productâconsequences that are moderately predictable based upon the specifics of the mutation. These consequences can range from benign (e.g. synonymous mutations) to catastrophic (e.g. frameshift mutations), with regard to protein production, composition, and function.
Point Mutations. A point mutation is a single-letter swap -- an exchange of two bases (adenine to cytosine, for example) at a single location in the DNA molecule. Since the sequence of letters in a gene determines the sequence of amino acids in the protein it encodes, a point mutation can change the amino acid sequence of the resulting protein. Sometimes a change in the protein's amino acid sequence can have dramatic results. For example, sickle cell disease occurs when a single-point mutation in the gene that encodes the hemoglobin molecule results in deformed red blood cells.
