"Living with Klinefelter Syndrome, Trisomy X and 47,XXY: A Guide for Individuals and Families to X and Y Chromosome Variations" is now available. It is a quite comprehensive overview of the genetics involved in X and Y chromosome aneuploidy, as well as providing information on medical issues, educational and psychosocial concerns, and transitioning to adulthood. Many participants of XXYTalk completed the online survey that helped to provide information covered in the book. It is available for order through Amazon (www.amazon.com) as well as on the KS&A website, www.genetic.org. My purpose in writing it was to make available a well-researched guide, particularly for those with new diagnoses and for parents with prenatal diagnoses. I have wanted to do this for the 25 years since my son, now an adult, was diagnosed when I was 5 months pregnant. It is currently being formatted for e-readers, and should be available on Amazon in a few weeks, if you prefer not to get a print copy. (added May 27, 2012)

After a long hiatus from this site that included relocation, a new job and marriage I am back and working again. This would have occurred much sooner, but because of a number of odd happenings, such as overwriting the boot sector of my hard drive, misplacing the passwords to my server space, and finally having the administrator of the site stop paying for the server space and having the site disappear along with the domain name . . . So here it is again, but as 47XXY.com. As of today all the links are current and every page is working. Any problems please contact me at 47xxyorg@gmail.com Thanks.  (January 20, 2008)
