Major Scientific Interests of the Group
Our laboratory is interested in genetics and
genomics of human autoimmune rheumatic diseases
such as ANCA-associated vasculitis, systemic lupus
erythematosus and systemic sclerosis. We are
taking advantage of genome-wide approach and
candidate gene approach in combination to identify
genomic variants associated with development of the
diseases, as well as those associated with their
serious complications such as interstitial lung
disease.
Currently, we are specifically interested in
susceptibility genes to ANCA-associated vasculitis
in east Asian populations, whose epidemiology
greatly differs from that in the European populations,
and largely unexplored. We are also interested in the
role of variations in the genes whose analysis
remains challenging, such as multigene families and
those with genomic structural variations.

●Our studies are expected to lead to better understanding of the pathogenesis of these enigmatic intractable
diseases, as well as to identification of molecular targets and biomarkers valuable in establishing future
precision medicine for human autoimmune rheumatic diseases.
