Those of us who learn about Klinefelter Syndrome at whatever age are in desperate need of finding others who share our situation. When you have a rarer variant, you need to be able to seek validation from others. In terms of information about these variants, again, there is very little. It is what we learn about ourselves and our similarities that can help all of us.
Below are some links for more information for those with one of these variants or a friend or family member with these rarer variants of Klinefelter Syndrome. If you have any recommendations for sites that have helped you, please feel free to let me know, and I will be glad to add to the resources below.
If you have any questions for me, please e-mail Stefan.
