Join this group if you are a parent of a son or daughter with one of the rarer variants multiple X & Y chromosome syndromes. That means X-X-X-Y, X-X-X-X-Y, X-Y-Y-Y, penta and tetra X.

If you are a x-x-y-y parent, contact us directly at amazonb@worldnet.att.net because we also have another group but I can't list it here because Yahoo doesn't allow anyone to use 2 x's in a row in a word. (Even though that other group yahoogroup address has always been that way!)

If your child has Klinefelter Syndrome, XYY or Triple X please contact www.aaksis.org and www.genetic.org. The XYY group also has 3 other Yahoo groups.
