The two main types of mutations are gene (point) mutations and chromosomal mutations.

- Gene (point) mutations: changes in the DNA sequence of a single gene (substitutions, insertions, deletions; can cause missense, nonsense, or silent changes).
- Chromosomal mutations: large-scale changes to chromosome structure or number (deletions, duplications, inversions, translocations, aneuploidy).
