The change in the DNA sequence involves a missense mutation, which means that there is a change in one of the amino acids encoded by the affected codon. The potential effects of the missense mutation cannot be determined without additional information about the specific amino acid change and its location within the protein. Therefore, it is classified as possibly having significant effects.
