At what age would you want to tell people they are no longer allowed to have children? Oh wait you probably want the inbreeding thing which is actually less of a risk than a 72 year old women having a child. Of course neither of these two concerns even apply to this case if you read the story but you have to be careful when going down the road in saying who should or shouldn't be allowed to reproduce.
Yeah i know its not relevant to this case. My response was to a slight derail in the thread to incest in general. I just did a cursory search on the risks associated with old women getting pregnant and this is what I found ... Not sure how reliable it is though.

That study is about women using donated eggs. As it relates to the topic of incest, unless the egg is donated from a third family member, there would be no additional risk if a women carried a child which is from the sperm of her brother/father/grandson/son/etc but not her own egg. The biggest issue with this particular case is that the woman is 72 years old and likely will not be able to fully raise her child.
But to the actual topic of inbreeding; yes there is reason for concern, especially when talking about multiple generations. However you also have to talk about it in context of what the real risk is (not so high for a single instance) and how it relates to other known risks for birth defect. The problem is that the taboo of incest has created a lot of myth and pseudo science around the topic of inbreeding. The risks are not as high as most people believe (and most don't even understand what the risk is) especially when talking about an isolated case and really do not warrant special treatment whereas many other risks are ignored as being the parents choice.
