Rolfe
Adult human female
She isn't transgender. You can argue that she was transgender, but she detransitioned. And again, she had a disorder of sexual development (deformed genitals). People like that constitute a vanishingly small fraction of the transgender community. They aren't where the actual conflict is.
She has some sort of DSD. The story as told suggests that when she was born she was actually recognised as being a girl, but someone thought it would be a good idea to let her be a boy (for all the advantages that would confer) because of her malformed genitals. It has seriously disturbing parallels to what that bastard Money did to the Reimer twins.
That's unusual. The more usual case is that a boy is misidentified as being a girl and brought up accordingly. Cases in point, Erik Schinneger and Caster Semenya.
I gather that Erik Schinneger accepts the label of being "trans", because he did transition from living as a woman to living as a man. But like her ladyship, what he did was correct a mistake and shift to living as the sex he always was.
In terms of actual trans-identification, that is moving to be seen as the sex you aren't, it seems that people with DSDs don't do this any more frequently than people without. It also seems likely that their motivations are different. The psychological problems that often seem to affect people with DSDs who have been insentitively treated as children could well be a significant factor in a later decision to transition.
