Quote:The Massachusetts research team, publishing in the journal Nature, used a procedure known as “genome editing” that allows DNA to effectively be cut and pasted to introduce a gene identified as XIST into the sample cells’ extra chromosomes.

XIST then caused a build up of a particular version of the RNA molecule, coating the chromosome and shutting it down. The cells, and with increasing proficiency, went on to correct for the extra chromosome 21. This research builds on previous findings that have shown the XIST gene’s crucial place in healthy human development.

Editing genomes within feti, if it ever comes to that, would have to be the next step in this science, I suppose.

If this is in humanity's future I'm sure it will cause interesting ethical and moral debates. I believe I heard on the radio, one woman with a down's syndrome child, stating that she would not want her child changed in any manner. However, pregnant woman who have not yet bonded with their child with physical challenges may not want to take the same path.
