He studied Mathematics, receiving his doctoral degree at Justus-Liebig-University in Giessen/Germany.

After the family’s return to Europe, he became a member of the German National Fragile X Association, which he is leading since 2009.

Jörg Richstein co-initiated the European Fragile X Network and was involved in the creation of Fragile X International, where he is currently serving as vice chair.

He is currently also chairing FraXI’s research committee.



Kristin Mulcock

My name is Kristin Mulcock and I am a board member of FraXI and Co-Chair of the Swiss Fragile X association FRAXAS since 2015. Our association joined the European Fragile X network in 2012, and taking part in our annual meetings really inspires me since then. I am a mother of 3 children, 2 boys (born in 1999 and 2006) and 1 girl (born in 2009). Both my boys have Fragile X Syndrome, but it affects them quite differently. Even though this diagnosis is a challenge for us as parents, we still realise how much joy and fun we have with and around our children, how many great people we have met through them, and how contagious their joy is in the little things in life. For me, the biggest challenge is the negative perception of people with special needs in our society and the one-sided focus on their limitations. Therefore, raising awareness and educating our fellow human beings is very close to my heart. If they dare to engage with our loved ones affected by Fragile X Syndrome, they may discover all by themselves how valuable and enriching they are.

Brendan Weight

Brendan lives in France with his family. He comes from a multicultural background: French, English and Irish. Brendan has a 20-year-old son with Fragile X Syndrome; they both share their love for rugby, having played and coached the game. Brendan has a business degree and worked in sales and project management in the IT industry for 25 years.

Brendan has been involved in Fragile X France since 2010 as a volunteer and since 2012 as treasurer and international contact. After joining the EFXN meetings in the early years, Brendon actively took part in the founding group to launch FraXI, where he currently chairs the International Relations Committee. His goal is to have as many associations as possible join our cause, and also to help families start a local fragile X organization in countries lacking them.



Françoise Goossens

Active since 2008 in the Belgian Fragile X association, Françoise Goossens has been appointed president of AXFB in 2020. She attended all international meetings of the European network starting in 2011 and was one of the founders of FraXI, through which FraXI was created in Brussels. As a Treasurer she takes over the financial and Belgian administrative aspects of the international non profit organisation.

Françoise is the mother of a Fragile X adult man. For more than 4 years she and her husband were looking for a correct diagnosis providing answers to the strange behaviour they observed with their son. They felt the diagnosis of fragile X syndrome as a relief in comparison to no diagnosis at all and further medical examinations.

Thanks to a former training in translation, she developed a multilingual glossary especially dedicated to Fragile X (EN - GE - FR). She currently works as a radioprotection officer in the radiopharmaceutical area.

Linus Mulcock

My name is Linus Mulcock, and I am 23 years old. I live in Nyon, Switzerland, and I have Fragile X syndrome. I have a brother (also with Fragile X syndrome) and a sister. At the moment, I work in a packaging workshop that does packaging for pharmaceutical and cosmetic products. I really like the work and the social contacts there. In my free time I take part in swimming training for Special Olympics and enjoy taking public transport to Geneva and the surrounding area. I am a board member of the Swiss Fragile X association FRAXAS and an expert to the FraXI board. My commitment to FraXI and FRAXAS motivates me a lot, and I have been to many European Fragile X network meetings in the past. I want to help raise awareness of Fragile X Syndrome, because we are often misunderstood and not treated the way we would like to be.
