| Outline of Final Research Achievements |
We performed homozygosity mapping for a consanguineous patient suffered from joint destruction using SNPs GeneChip array compared with a healthy patient brother. We detected 2049 candidate genes in this study. As we could not narrow down the candidate genes in homozygosity mapping, we examined the candidate genes using next generation sequencing. We could detect 10 candidate genes from 11 locuses in this system, and narrow down and confirm 6 missense mutations after Sanger sequencing. Moreover, we confirmed the 5 gene expressions from 6 candidate genes using RT-PCR in both chondrocytes and osteoblasts.To know the role of pathophysiology in this arthropathy, we planned to establish the iPS cells. Several clones of the iPS cells derived from a patient were established in CiRA (Center for iPS Cell Research and Application, Kyoto University). After we received iPS cells from CiRA, we tried to differentiate into chondrocytes, osteoblasts, and osteoclasts.
