A Revolutionary New Technique May Help Treat Down Syndrome
Researchers have achieved a remarkable scientific breakthrough by deleting an extra chromosome in lab-grown cells, raising hope for the development of future treatments for Down syndrome using advanced gene-editing technologies.

Down syndrome occurs when a person is born with three copies of chromosome 21 instead of the usual two, which affects brain development and causes intellectual disabilities, learning difficulties, and other health challenges.
Scientists from Meiji University in Japan used the revolutionary CRISPR-Cas9 technique—often described as a "molecular scissors"—to remove the extra chromosome in the cells. The designed system was able to distinguish the duplicated chromosome from the original two copies inherited from the parents, ensuring that the cell retains one copy from each parent instead of two identical copies.
