Another term for "transgender children"

Is there another expression besides "transgender" that is widely accepted in US English for children of all ages and both sexes, which deal with doubts about their gender and body while they grow up?

Wikipedia offers many options:

  • Agender / genderless
  • Androgyne
  • Bigender
  • Genderqueer / Non-binary
  • Gender bender
  • Hijra
  • Pangender
  • Queer heterosexuality
  • Third gender
  • Trans man
  • Trans woman
  • Transmasculine
  • Transfeminine
  • Trigender
  • Two-Spirit…

I am not sure if any of those is specifically for children, and I need one meant for children.

How would be called a child in US English, who wants a sex change, but not for the same reason as other transgender children (he grieves after his sister, feels guilty for her death and wants to replace her, so his parents remain together)?

It is a script idea I am working on at the moment.


If the word existed, Wiki wouldn't need to use an acronym: GIDC. It'd at least have a more scientific sounding name like, Adolescent Gender Dysphoria, but that would exclude anyone who's prepubescent, which is probably why it's not.

Gender dysphoria in children –Wiki

Gender dysphoria in children or gender identity disorder in children (GIDC) is a formal diagnosis used by psychologists and physicians to describe children who experience significant discontent (gender dysphoria) with their biological sex, assigned gender, or both.
