Fine Motion from Uma Musume: Pretty Derby is canonically intersex-coded, and she has an unidentified chromosomal variation!
The requester elaborates: "All umas are based off real racehorses, you can tell their real life sex by whether their hair accessory is on the left (male) or right (female). Fine Motion has accessories on both sides of the head, alluding to the fact that the real life horse Fine Motion was found infertile due to a "chromosome defect'. The creators of Uma Musume consult with the owners of the horses before designing them, so it's probable the owners decided this choice."
