Wright @ Duke University Re: Down's Syndrome I don't think that the submitter meant that the problem was equally likely to affect the children of older women as younger women, but to emphasize that the ultimate cause of the problem is not known (yes, I know that it's caused by an extra chromosome, that's not what I mean!).
