Malaysian scientist Thein Swee Lay wins Breakthrough Prize for gene therapy breakthroughs
The 'Oscars of science' awarded to the first Malaysian for turning deadly blood disorders into treatable conditions.
Dr. Thein Swee Lay, born in Kuantan, Malaysia, has become the first Malaysian to win the Breakthrough Prize, a prestigious award often dubbed the 'Oscars of science'. Now 74 and based at the National Institutes of Health in Bethesda, Maryland, she was recognized in 2026 for her groundbreaking research that unraveled a decades-old mystery in blood disorders. Her work paved the way for gene-editing therapies that have transformed sickle cell disease and beta-thalassaemia from life-threatening conditions into treatable illnesses.
Thein, the seventh of nine children, credits her adaptability to her family's frequent moves across Malaya due to her father's civil service postings. In an exclusive interview, she fondly reminisced about her childhood in Kuantan, noting that her only struggle in the U.S. has been finding authentic Malaysian popiah. Despite the geographical distance, her impact on global medicine is profound: she has helped millions of patients worldwide by enabling targeted gene therapies that correct the underlying genetic mutations causing these blood disorders.
- Dr. Thein Swee Lay is the first Malaysian to win the Breakthrough Prize (2026), worth $3 million.
- Her research enabled gene-editing treatments for sickle cell disease and beta-thalassaemia, affecting over 300,000 births annually worldwide.
- She has lived in Washington D.C. since 2015 and works at the NIH, a result of her career adaptability from frequent childhood relocations.
