| Outline of Final Research Achievements |
We established a system to communicate with Dr. Duan Lian, Professor and Chief, Center for CVD in 302 PLA Hospital, Beijing, China, who are now treating world most number of patients with moyamoya disease. Although gene mutation, RNF213 (p.R4859K), exist in more than 80 % of Japanese patients, our analysis revealed that it was detected only in 15% of Chinese patients. Our whole exon sequence analysis could lead to the finding of CCER2 gene as a novel susceptible one for moyamoya disease. We could get information on the detection of the other several novel susceptible gene mutation that were detected in Chinese patients, although it has not been published yet.
We also could achieve another purpose of the present grant by establishing the system to use the same non-invasive cerebral perfusion measurement method by DSC-MRI and ASL-MRI.
