Laboratory Introduction

Our mission is to develop an infrastructure for realization of personalized prevention and medicine in the devastated areas by the great east Japan earthquake. To do so, we use genetic and omics information of the participants of prospective cohort in the damaged area to identify the susceptible loci for the common disease which is aggravating in the area. We have successfully sequenced the genomes of thousands of healthy participants and have constructed the whole-genome reference panel of Japanese population. Now we move to the analyses of relationship between genomic alterations and disease susceptibility and elucidation of molecular networks associated with disease mechanisms. We are expecting several millions of single nucleotide variants in an individual’s genome and some of them might be associated with disease onset. By means of integration of omics analyses, we will try to narrow down the candidate genes. Finally, we will try to identify disease susceptible genes for the cohort participants and give them the appropriate information for their health care.
