A place of hope, support, and understanding. For over three decades, we’ve been uniting families affected by chromosome 18 conditions, creating a worldwide network of over 6,000 families. Here, you’ll find a community that truly understands your experiences, offering a shared journey of learning, support, and hope.
Our mission is centered on three pillars: nurturing a compassionate community, enhancing education, and driving innovative research. We aspire to make chromosome 18 abnormalities the first treatable chromosome condition, working towards a future where everyone can achieve their full potential.
You’re not alone in this journey – join us in our vibrant social media groups, virtual events, regional meet-ups, and our enriching Annual Family Camp. This website is your resource, guiding you with unique tools and information to support your Chromosome 18 journey.
