A missense mutation is a type of point mutation that results in a different amino acid being incorporated in the protein. In this case, the mutation changes TAT (tyrosine) to CAT (histidine). A frameshift mutation would result in a shift in the reading frame and probably produce a completely different amino acid sequence, while a nonsense mutation would result in a premature stop codon, leading to a truncated protein. A silent mutation would not result in any change in the protein sequence as it codes for the same amino acid.
