🧬 Sickle cell did NOT begin in 1910. ...and it didn’t begin in America!
Its story goes back thousands of years—to human genetics, malaria, survival, migration, and generations of families across the world. 🌍
Here’s the story 👉🏾
🌍 ORIGINS: The sickle hemoglobin variant (HbS) arose in malaria-endemic regions, including multiple regions of Africa. Over generations, human movement carried HbS around the world.
🔬 1910 WASN’T THE BEGINNING: Walter Clement Noel, a dental student from Grenada, became the patient behind the landmark 1910 Western medical description of sickled red blood cells. The disease existed long before Western medicine documented it.
🦟 WHY MALARIA MATTERS: One copy of HbS—sickle cell trait—provided some protection against severe malaria. That survival advantage helped HbS persist across generations.
🧬 ONE SMALL GENETIC CHANGE: A change in the HBB gene produces HbS. When certain hemoglobin variants are inherited together, they can cause .
❤️ AND THE STORY IS STILL BEING WRITTEN.
Today we have , disease-modifying therapies, stem cell transplantation, gene therapies, and a much deeper understanding of sickle cell disease than generations before us had.
But scientific progress only matters when people can access it...
From an ancient genetic adaptation to a global community—and now to treatments and curative therapies once unimaginable:
This is the origin story of disease.
