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.
1 Missense mutations or nonsynonymous mutations are types of point mutations where a single nucleotide is changed to cause substitution of a different amino acid. 2  This in turn can render the resulting protein nonfunctional.
