Scientists Silence Extra Chromosome In Down Syndrome Cells

An anonymous reader writes "Scientists have silenced the extra copy of a chromosome that causes Down syndrome in laboratory stem cells, offering the first evidence that it may be possible to correct the genes responsible for the disorder. The discovery provides the first evidence that the underlying genetic defect responsible for Down syndrome can be suppressed in cells in culture."

Maybe some aspects of Downs could be reversed, but as many of the neurological and physiological aspects of the disorder are doubtless developmental, I can't imagine any substantial changes to a person already with the syndrome. The greatest hope, I imagine, is in utero treatment which would prevent the developmental aspects of Downs Syndrome from happening at all.
