| Outline of Final Research Achievements |
Aggressive periodontitis(AgP) is a particularly severe type of periodontitis and diagnosed by three characteristics: rapid bone destruction, possible familial aggregation, and absence of other systemic disorders in the patient. Exome sequencing is increasingly utilized as tools in genetic research and has a potential to determine the genetic cause for both single gene and complex disorders. Of 119 patients who diagnosed as AgP, we found 3-generation consanguineous pedigree in which three of them are affected with AgP. We further performed whole-exome sequencing in those three AgP patients and one control. (Two of them are already sequenced. Lest of two will be sequenced near future.) After getting sequencing data, we plan to analyze them by using a bioinformatics pipeline.48889 and 45564 variants are found respectively, in two patients.
