While it's not new that genes can be associated with different products in distinct (and not directly related) body systems, the research begins to put this into context more generally. The part that's always fascinated me is the potential massive permutation of protein interactions. For example, the proteins are commonly enzymes or components of cell membrane receptors. Variations in these kinds of proteins affect how other proteins can do their jobs, so multiplied over and over, the end results become wildly unpredictable. In science the pace never stops, it just gets more and more interesting...
