Summary of Activity

We conduct genetic investigation on human genetic / congenital disorders, in collaboration with Center for Medical Genetics, Shinshu University Hospital. The main theme is to "hunt disease-causing genses" through careful clinical assessment and advanced genetic analyses including next-generation sequencing. Together with clinical studies on these disorders, we aim to make a contribution to establish a society where these patients can live healthy and happy lives.

Research Subject

  • ? Comprehensive study of hereditary connective tissue disorders, especially Ehlers-Danlos Syndrome Kosho type (musculocontractural EDS-CHST14)
  • ? Genetic investigation for intellectual disabilities (ID), autism spectrum disorders (ASD), epilepsy, congenital malformation syndromes, and adult neurological disorders
  • ? Molecular cytogenetic investigation including microarray and FISH

Outlook for Research

The best part of clinical genetics is to establish a new disease entity from only one patient.
To find the disease-causing gene could be a breakthrough in understanding the pathophysiology of the disease, developing innovative therapies, and uncovering relevant biological bases.

Outlook for Students After Graduation

After obtaining a medical specialist such as a pediatrician, you can enter our “clinical genetics” course where you have sufficient training for clinical, cytogenetic, and molecular genetics to obtain a certified clinical geneticist.
