They would have to fight even harder than they do now to overcome the same barriers that plague the whole set of candidates for gender reassignment.

Sadly, I can now see a scenario where this discovery may well lead to a situation where the subset of those candidates who have the gene markers will find the road to surgery made a little easier, at the expense of a thickening of the glass wall for those belonging to the remainder of the set of candidates who do not.

So, overall, that is a minus.

Shit.
