Type 1: Point mutation — a change of a single nucleotide in the DNA (a substitution). Can be silent (no amino‑acid change), missense (different amino acid), or nonsense (creates a stop codon), so its effect on the protein ranges from none to truncated/nonfunctional.

Type 2: Frameshift mutation — insertion or deletion of nucleotides not in multiples of three, which shifts the reading frame of the codons. This changes every downstream amino acid and usually produces a nonfunctional protein or an early stop.
