More Details

To a growing number of people, the letters “KS&A” stand for Knowledge Support & Action.  KS&A is the nation’s oldest and largest non-profit organization serving individuals and families affected by an uncommon number of X and/or Y chromosomes, including 47,XXY, Klinefelter syndrome, Trisomy X, 47,XYY, mosaicism and other associated conditions.

KS&A received its start on April 12, 1989, when nationally syndicated columnist Ann Landers published a letter written by the concerned mother of a then 8-year old 47,XXY son.

Within weeks, more than a thousand letters poured in from individuals all over the country who were affected by these conditions and other parents who expressed similar concerns with the lack of timely diagnosis, inaccurate information and poor support services for affected persons.  KS&A was formed shortly thereafter, and has operated continuously ever since.

What began as an effort by one concerned individual to locate information and support, has grown into an international support organization that today responds to calls and inquiries from persons who are just learning of the diagnosis, sponsors conferences and other events that are directed to the needs and interests of the individuals affected by these conditions, their families, and the clinicians, educators and researchers who serve them, and much more….
