High Country Disease, also known as brisket disease, can be debilitating for cattle when they're moved to high elevations. While it's possible to select cattle based on their PAP (pulmonary arterial pressure) scores, collecting PAP data is an involved process. That's why a consortium of researchers are hunting the genetics of the disease. Jonathan Beever, a geneticist with the University of Illinois, thinks they're close to finding the genes responsible and that a genetic marker test could be available soon.
