Fascinating. Thanks for posting.

You're quite welcome. This sentence from the article stymied me: "The researchers say that although the mutation is found in vastly different ethnic populations,..."

Turks, Jews and Arabs are not "vastly different;" they all appear to have originated in the Near East. Perhaps this mutation is also present in, say, Hmong tribesmen or Orkney Islanders, but that is not said, and I do not think that is the case.
