A new hope in reproductive technology

Prospective parents hoping to avoid downs syndrome may eventually get a treatment option on top Preimplantation Genetic Diagnosis(PGD).
PGD offers only the ability to reject embryos with adverse genetic variations or alleles, but according to Scientific American, researchers have been able to shut down the extra chromosome by adding a extra gene. Thus making the genes responsible for Down's Syndrome silent or non-expressive.  This may be very important for parents who struggle to produce eggs or produce ova that are all affected. Given the difficulty of the preparation for an invitro cycle this may save couples a lot of grief, extra cycles and extra cost.
