03/21 - at the 21st chromosome, there is a third replication instead of a pair of genes - this is how a person has the genetic alteration commonly referred to as “Down Syndrome” aka “Trisomy 21.”
Happy World Down Syndrome Day!
Today is World Down Syndrome Day — and we are proud to stand together with our partners the National Down Syndrome Society and the Down's Syndrome Association. 💙🩷
This year's theme — Together Against Loneliness — has touched something deep. People with Down syndrome and their families around the world have told us: this is our story. This is what we live. And this is what we want to change.
Loneliness is not just a feeling. It is a human rights issue. And together, our network of 160+ organisations across the globe is committed to making real change happen — so that every person with Down syndrome feels included, valued, and truly connected.
Today, we celebrate our community. And we renew our commitment to a world where no one is left out. 💛
Together Against Loneliness. Together for change.
