Personalized Medicine - What Are the Challenges?

One big challenge right now is the region of the genome that does not encode information. People typically look for recurring motifs of a sequence, which is a block of nucleotides with certain probability in its position. But unfortunately, these tools are really not foolproof right now. And we do need to go in the bench and do it physically and try to fish out specific regions that bind the specific protein that we're interested in.
