Deletion or addition mutation
Weba frameshift deletion at the beginning of the gene- it would affect every codon after the point where the mutation occurred. During protein synthesis, incorrect amino acids would be inserted from the point where the frameshift mutation occurred on; the resulting protein would most probably be nonfunctional.
