Not to mention normal women and normal men!
I don’t know what the best term would be - I understand “intersex” is in disfavor - but it’s probably not “transgender,” because gender is either a linguistic category or a social construct, while the issue for people with variant sex chromosomes is solidly biological.
Maybe trans-sex, or bring back intersex. With the odd chromosome combinations and abnormalities, you cannot really put them into the either-or category.
