| Research Abstract |
It is known that congenital missing of permanent teeth is one of the most popular anomalies in craniofacial region. Lacking of many teeth (oligodontia) causes serious dysfunction to the mastication, pronounciation and food intake. In this study, we identified a novel gene mutation (321_322insG) in a transcription factor, PAX9. This mutaion was unstable and had a shorter half life than wild-type PAX9.
