What is Sickle Cell?

Sickle Cell disease is a heritable blood disorder caused by a beta-globin gene mutation that produces sickle-shaped red blood cells. This abnormal hemoglobin can lead to painful crises, anemia, and various organ complications over time.

Clinically, Sickle Cell disease often features episodic pain, infection risk, and possible organ complications, requiring ongoing medical surveillance, vaccination, and lifestyle adjustments. In India, early access to newborn screening and specialist care can improve outcomes.
