Fan Casting Abandon the Disabled in Sort by Tropes

A character with a disability or deformity is abandoned by their family or caretakers. It could be that the character's parents can't afford their child's extra costs, they don't want a disabled individual, they think the child is cursed, or they don't want to deal with the personal loss of having their child die. Parents who want perfect Trophy Children will do this in extreme cases if they don't instead hide away their child from public view.
