In 1959 Dr. Patricia Jacobs and her team in Edinburgh, Scotland at the Western General Hospital, coined Triple-X as the name of the syndrome. Ever since there has been quite some scientific research. But a medicine or “cure” does not exist. Hundred thousands of families each on their own go through life with a third x-chromosome (47, xxx)  in one of their daughters, siblings, wives, or partners. Every 1000th woman on earth is born with it, only about 10% are diagnosed, often by chance. But that there is no “cure” does not mean that there is no approach to support and improve life with Triple-X and this network will off many strategies that are already in practice worldwide.

AXYS has a brochure, which gives a good overview.

The Rare Chromosome Disorder Support Group (UK) has prepared a 16 page documentation on XXX.
