Hypokinetic movements include: 1  Bradykinesia. 2  Freezing. 3  Rigidity. 4  Postural instability.
1 Missense-the change in nucleotide leads for a different amino acid. 2  This may have little effect, or it may greatly change the resulting protein. 3  Silent-this type of point mutation is the least harmful as there is no noticeable effect on the protein.
Mutations which affect an organism are often categorized into two basic types: loss-of-function mutations and gain-of-function mutations. A loss-of-function mutation is âa mutation that results in reduced or abolished protein functionâ.
