| Research Abstract |
In order to establish reliable technologies for typing nucleotide sequence polymorphisms, we first developed a new typing system for the HLA-DRB1 gene, which shows a highest degree of polymorphism and significant associations with many diseases. A glass array with a chamber made the typing procedure similar to that for microtiter plates. Next we developed a micro-capillary array for the typing of disease-associated SNPs. Many different oligonucleotide probes were spotted in each capillary, and each probe provided a specific hybridization signal after washing through a capillary. Thus this system may be suitable for multiplex and automated SNP typing. In addition, we could establish a new SNP typing system in the combination of PCR-SSP with the fluorescence correlation spectroscopy. The system has been introduced to routine SNP typing and proved to be a large-scale and cost-effective system. Furthermore, we have identified several rheumatic disease-associated SNPs including those of FCGR2B, FCGR3A and LIR1 genes.
