One consequence could be a change in the wizard or witch's magical abilities. Since parents play a role in a wizard's heritage, changing them might mess with their natural powers. Another could be a shift in their social standing within the wizarding world.
Well, in most fanfics, it might involve complex incantations and rare magical ingredients. Maybe something like a special potion made from enchanted herbs and a spell cast under a full moon. But it's all just fan - created ideas and not part of the official Potter lore.
In this fanfic, a student at Hogwarts might be bullied because of their parents' status. They come across a magical ritual that is said to be able to change the very essence of a person.

Dark forces start to seep into the wizarding world, and the student realizes they must fix the ritual's effects before it's too late.

Well, 'the ritual' in the Harry Potter fanfic could be some kind of dark magic ritual. Maybe it's a plot device used by the villains in the story.

However, without more context from the specific fanfic, it's hard to be more precise.
One possible fanfic could be about Harry's parents being magically changed in appearance. Maybe they were cursed by a dark wizard and had to live with different looks.
