Some people have few effects.  Others may be affected more.

Three quarters of people  who have KS/XXY never find out that they have it. You are lucky to have been diagnosed because you will get  medical help and support, if you need it.

KS/XXY can have some effects on your body, how you feel, and how you communicate.

It may be sensible to wait until you really know people well before you tell them about having KS/XXY. It isn’t anything to be ashamed of but you might be teased about being ‘different’ – just like people with red hair can.
