Can Down Syndrome Be Eradicated? Facts on Japanese Research Claim
“children with down syndrome may no longer be born. Japanese have managed to remove the chromosome linked to this condition”
Summary
Japanese researchers have only demonstrated removal of the extra chromosome 21 from laboratory‑grown human cells using CRISPR; the technique has not been applied to embryos or clinical pregnancies. There is no evidence that this will stop children with Down syndrome from being born, making the statement an exaggerated interpretation of an in‑vitro study.

It also supports earlier findings that extra copies of chromosome 21 disrupt brain development during early fetal growth. ... The researchers didn't just test their approach on lab-grown stem cells. They also applied it to skin fibroblasts, which are more mature, non-stem cells taken from people with Down syndrome. Even in these fully developed cells, the method successfully removed the extra chromosome in a significant number of cases.
