RHEUMATOID ARTHRITIS DISEASE SENSITIVE GENE, ITS PROTEIN, METHOD AND KIT OF JUDGING THE ONSET OF RHEUMATOID ARTHRITIS USING THE SAME, AND METHOD AND DRUGS FOR TREATING RHEUMATOID ARTHRITIS

摘要

An gene was identified as a RA disease susceptibility gene on Human Chromosome 8, the gene coding a protein that has an amino acid sequence shown in SEQ. ID NO.1 and that has such mutation that glycine is inserted as a 269th amino acid in the sequence. Moreover, it was found that mutation of the gene and the protein relate to onset of RA. Achieved is a method of evaluating with high accuracy the onset or onset possibility of RA by using the mutation.
