| Outline of Final Research Achievements |
During the fiscal year of 2013-2015, we have done genome-wide association study of alopecia areata (AA) patients by utilizing microsatellite markers. In addition, we have also examined by using SNP markers and next-generation sequencing, and have obtained below-mentioned results.
1) We have identified strongest association of AA at HLA-C locus within HLA lesion (OR: 3.41). 2) 28 haplotypes were detected, and 1 of them was found to contain responsible gene for AA. 3) 5 risk and 3 non-risk haplotypes were examined by next generation sequencer, and an exonic non-synonymous single nucleotide variant, which was common to all risk haplotype, was only detected. We are now trying to generate gene modified mouse model, and examine its phenotype.
