Due to system maintenance, the application system, application review by the Data Access Committee will be unavailable during the following period.
Schedule: October 5th (Mon), 2026, 9:00 - October 7th (Wed), 2026, 15:00 (JST)
We apologize for any inconvenience this may cause and appreciate your understanding.

We are currently receiving a large number of applications for data submission, and the review process is taking longer than usual.We sincerely apologize for the delay and kindly ask for your understanding. When submitting an application, we would greatly appreciate it if you could allow sufficient time for the processing.

Following a change to our organizational structure effective April 1, 2026, this division has been renamed from the "Database Center for Life Science, Joint Support-Center for Data Science Research" to the "Database Division for Life Science (DBCLS), BioData Science Initiative (BSI), National Institute of Genetics (NIG)". Where the former name still appears in the guidelines, please read it as the new name.

QC for reference panel:
After excluding 11 closely related individuals, variants with HWE P < 1.0 x 10^-6, MAF < 0.01 were excluded.
QC after imputation:
Variants with imputation quality of Rsq < 0.7 and MAF < 0.01 were excluded.
Imputation
minimac [imputation (1000 genomes Phase I v3)]
Analysis method
GenCall software (GenomeStudio)
