In general, I don't like the idea of so much genetically altered humans (and less so generalized) as MgT 2300AD depicts, but that's a matter of personal tastes, not a rules flaw.
Even so, there are some side effects that I'm not sure have been weighted enough when using them:
Gender reassignment:
I see this as one of the most difficult genetic manipulations on an adult, as we're talking her about replacing a full cromosome (either an Y to X or vice-versa), not just some genes. This aside, the major anatomic changes it means would probably need major surgery, aside from any genetic/cromosomic changes (so making difficult to reverse them and, IMHO, the gender hoping told about in page 127 quite risky at least...)
According to page 123, major modifications are only interfertile with someone who has received the same modification. When we try to apply this to gender reassignment we find some curious results:
See that in the latter case (being freely interfertile with "normal" humans), if we apply the these changes are permanent and are passed along to successive generations (also in page 123) would mean that all chidren would be the same gender of the modified parent, while if we try to apply this sentence to option 2 (interbreading among people haveing undergone gender reassignment on oppopite ways) this result could be even more funny...
Thoughts?

- They are infertile, as, being only interfertile with someone who received the same modification would mean being only interfertile with people of the same (modified) gender...
- Alternatively, they could interbreed with someone having undergone gender reassignement (on the opposite way), so leading us to a former male begetting a child from a former female :CoW:...
- Alternatively, we could assume that being a full cromosomic change with no true genetic changes (no alien genes to a human genoma being introduced), this is an exception to the non-interfertile rules.
