| Outline of Final Research Achievements |
We investigated craniofacial features with glucose transporter 1 deficiency syndrome (GLUT1-DS), which is an autosomal dominant genetic disease. Cross sectional study was performed using 9 GLUT1-DS patients, aged from 8 to 49 years old. All of the participants underwent intraoral and radiographic examinations. Lateral cephalogram measurement was performed for investigating possible craniofacial features in GLUT1-DS patients. Most of them showed skeletal discrepancy with large overjet.
However, we could not find a clear correlation between the type of mutation and the craniofacial features, such as malocclusion severity in this study. This failure could be due to the small sample size and it may be possible to find a genotype and craniofacial phenotype correlation in the future by increasing the number of samples and performing detailed craniofacial analysis.

| Academic Significance and Societal Importance of the Research Achievements |
本疾患のように咬合異常との関連が明らかとなっていない疾患において、その原因を解明することは早期治療やより有効で根本的な分子標的薬の探索や遺伝子治療に応用できる可能性が期待でき、非常に高い意義をもつと考えられる。
