| Outline of Final Research Achievements |
The association of the ATP10A gene was suggested by genome-wide methylation analysis in the case of sudden infant death. Furthermore, methylation analysis of 16 CpG sites of 8 genes (ELOVL2, CCDC10, C1orf1, FHL2, ASPA, F5, KLF14, PDE4C) could estimate the age of the donor within ± 6 years. Finally, the "Methylation Panel" which could analyze these at once was established.

| Academic Significance and Societal Importance of the Research Achievements |
死因の判断が困難な乳幼児の突然死例において，メチル化解析により新たなバイオマーカーとなり得るATP10A遺伝子の関連が示唆され，今後の研究が期待される．また，現場に残された生体試料から由来者の年齢推定が±６歳の精度で可能となり，犯罪捜査において非常に有用な方法が確立された．このように本研究の成果は，即座に法医実務に応用可能なものであり，メチル化解析の応用は今後さらなる発展が期待される．
