In 2006, the lab of Dr. David Ginsburg at the Life Sciences Institute put a call out for siblings attending the University of Michigan to donate blood for a study of blood-clotting disorders. The samples were collected over three years and have now enabled the researchers to identify the specific parts of the genome responsible for levels of a key substance for blood clotting. The findings were reported online Dec. 24 in the Proceedings of the National Academy of Sciences.
