Genomic: polyploidy, heteroploidy (monosomy, trisomy, polysomy).
Gene (point): replacement of a pair of nucleotides, insertion of a new pair (shift of the reading frame), loss of a pair of nucleotides.

There are other classifications of mutations. For example: nuclear and cytoplasmic, neutral, useful and harmful, somatic and generative.
