Every step helps build knowledge
The newest member of our family is Sien.
Sien is a happy and curious 16-month-old little girl. She is Jack's granddaughter and Edith's grandniece. Shortly after she was born, she was diagnosed with Smith-Magenis Syndrome (SMS), a rare genetic condition.
She is surrounded by loving parents, family and friends, and receives specialist support from the Expertise Centre of 's Heeren Loo in the Netherlands. That expertise matters.
For many rare genetic syndromes, there is currently no cure. Progress comes from research, from understanding genetic changes more deeply, and from sharing knowledge between researchers, healthcare professionals and families. Every new insight helps improve diagnosis, support and care for people living with rare genetic conditions.
That is why we are running. On 15 November 2026, we will take part in the Larnaca Half Marathon in Cyprus. Our goal is not to win, but to raise awareness and support research, knowledge sharing and better care for people living with rare genetic syndromes.
Every donation, no matter the size, helps move that work forward.
In the updates at the bottom of this page, we’ll tell you more about Sien, SMS, the Centre of Expertise, who we are, and of course our journey towards the half-marathon. So keep scrolling and follow along!
Thank you for joining us on this journey,
Jack & Edith
