GEM Japan

The GEM Japan project, which has covered Program for an Integrated Database of Clinical and Genomic Information, Platform Program for Promotion of Genome Medicine, BioBank Japan Project for Genomic and Clinical Research, Tohoku Medical Megabank Project in Japan, plans to share the allele frequencies as well as disease variations of Japanese population, and has held GEM Japan workshops in order to localize the GA4GH tools into non-English speaking countries.

  • TogoVar (Integrated database of Japanese genomic variation) : A database that has collected and organized genome sequence differences between individuals (variants), which has been developed as a joint research project of National Bioscience Database Center (NBDC), JST, and Database Center for Life Science (DBCLS), ROIS.
  • MGeND(Medical Genomics Japan Variant Database) : A database aiming to provide the integrated information of genomic variations and clinical characteristics, which has been developed by the AMED program for an Integrated Database of Clinical and Genomic Information.
  • BBJ(BioBank Japan) : One of the three major biobanks in Japan managed by the AMED BioBank Japan Project for Genomic and Clinical Research.It has collected DNA, serum and clinical information from more than 270,000 patients nationwide, and thus is regarded as one of the largest disease biobanks in the world.
  • TMM (Tohoku Medical Megabank Project) : The project conducts a long-term health study of a total of 150,000 residents living in communities which suffered major damage from the Great East Japan Earthquake and reports the findings to the respective residents with their personal information. It also establishes a system of dispatching physicians on a rotation basis to health care providers in the region.
