Study maps biological differences in Down syndrome co-occurring conditions

For generations, Down syndrome has been understood as a single condition, yet the people who live with it have always told a more varied story through their bodies. Scientists at the University of Colorado have now given that variation a molecular language, mapping how an extra chromosome interacts with obesity, heart disease, and immune dysfunction to produce radically different biological profiles across individuals. The work, published in Nature Communications, marks a turning point in the long effort to move from a one-size-fits-all approach toward medicine that meets each person where the
