Well in that link it said that usually people with differen't coloured eyes have a hearing problem but I have differen't coloured eyes (my right one is blue and my left one is a hazel green colour) and I have amazing hearing! So it dosen't mean that everyone with differen't coloured eyes have a hearing problem.....Waardenburg syndrome gives you hearing loss. It does not make you any less of a person tham other people.

Same with my brother XPWell, I've never had permanent hearing loss; But when I was very young I was constantly getting ear infections and was very hard of hearing. Eventually the doctors operated and put these tubes in my ear.
