These sequences carry huge information that could be applied to personalized medicine, Skolnick says. However, this potential is unrealized, because many genetic variations in the exome are of unknown significance. With appropriate tools to annotate the exome, scientists can determine which variations might be significantly related to disease and what diseases might be caused by certain variations.\u003C\/p\u003E\u003Cp dir=\u0022ltr\u0022\u003ESkolnick, who is also director of the College of Sciences\u2019 \u003Ca href=\u0022http:\/\/cssb.biology.gatech.edu\/skolnick\/people\/jeff.html\u0022\u003ECenter for the Study of Systems Biology\u003C\/a\u003E, is an expert in bioinformatics.
