In some cases, that's simply not true.  We know that one specific
and very short gene sequence produces a defective protein, or fails
to produce a protein, where a slightly different sequence gives the
proper results.  Change that bit of damage and nothing else, and there
are no other changes.  Or people can have extra copies of a specific
gene, and the overproduction of a protein causes other problems.
If one could delete the extra copies of that gene, and make no other
changes, the person would be better off.

See this, for example:

The crucial factor is being able to make changes very specifically.
