This is the website of the Dutch informal contact group for people involved with trisomy X, also called triple X syndrome or 47,XXX.

We are a small group, founded by two mothers of girls with trisomy X: Thea and Ida. Their daughters are now young adults. The team also has a webmaster, Jessica. We provide information and possibilities to share experiences and learn from each other. Our language is Dutch. We have a Facebook group in Dutch, a newsletter and we organize in person meetings about every other year.

For information in English, we refer to our colleagues:
