To get a better grip on his ancestry and predisposition to disease, Albert Zink, head of the Institute for Mummies and the Iceman in Bolzano, and his team sequenced Ötzi’s 3 billion base pair nuclear genome from a shard of hip bone. Their sequence covers more than 90 percent of the Iceman’s genome. Their team also analysed DNA preserved in Ötzi’s stomach in hopes of revealing the microbes that colonized his gut.
Zink says his team is keeping most of the results of these studies under wraps, pending publication. They had hoped to have the paper out in time for last week’s Mummy Congress and a television special called Iceman Murder Mystery.
His team plans to use the sequence to determine Ötzi’s status for genetic variations linked to diseases in modern humans, particularly arthrosclerosis. A full nuclear genome will also paint a more detailed picture of the Iceman’s ancestry and his relationship to present-day humans. Zink’s team will ask whether Ötzi is an ancestor of people living in Central Europe today, or whether he and his kin died out and were replaced by migrants from elsewhere, such as the Middle East. To buff up this analysis, they are analysing DNA preserved in the skeletons of other ancient inhabitants of central Europe.
I don't get why we can't have Otzi's genome sequence out in the open already. I realize that it's a precious resource that can lead to lots of publications for the people involved, but at the expense of delaying the use of the genome by everyone else. Otzi wasn't a milk drinker but he is sure as hell being milked dry by the people in charge.
