variants 48XXXY and 48XXYY

INFORMATION FOR THOSE WITH
VARIANTS OF 48XXXY AND 48XXYY

Those of us who learn about Klinefelter Syndrome at whatever age are in desparate need of finding others that share our situation. When you have a variant, it is rarer than being 47XXY and in terms of both number of people the number of those with this variant is much less. In terms of information about these variants, again there is very little. More importantly, it is what we learn about ourselves and our similarities that can help all of us.

This section lists e-mail addresses and other contact information for those with 48XXXY or 48XXYY variants.

It is important for us to be able to seek validation from others with this variant of Klinefelter Syndrome.

If you are affected by this variant or if your son is affected and you would like to be listed, e-mail Stefan. Please let me know via e-mail if you come across any email addresses that are no longer valid, so I may modify them accordingly. Thanks so much.

A recent listserv has been started for the 48XXXY variant. The listserv can be found through this link.
