If I understand correctly, it's a pre-existing gene that is modified by its removal / isolation. It appears to be an incredibly subtle change that in no way alters the fundamental characteristics of the gene itself. So yes, by extension they would hold no copyright over the genes in a given person's body, but it might extend to cover any tests or work that is done with those genes in the body - such as cancer screening tests.
