| Title | HLA-DRB1, -DQA1, -DQBl, =-DPA1 and -DPBl genes in Japanese multiple sclerosis patients |
Results of multiple sclerosis :
| Risk Type | Disease risk |
| Main Result | Negative |
| Result | Japanese MS patients and controls were examined for the distribution of HLA-DRBl, -DQAl, - DQBl, -DPAl and -DPB1 alleles using in vitro amplification of genomic DNA and probing with sequence-specific oligonucleotides. No significant difference in frequency of the examined alleles was observed among the two groups. |
| Mechanism/Pathway | Recently, we reported that among Norwegian MS patients the disease may be more closely associated to certain combi- nations of DQAl and DQBl alleles (i.e. DQA1*0102, *0103, *0401 or *0501 in combi- nation with DQB1*0602, *0603, *0604, *0302 or *0303). In fact, 96% of Norwegian MS patients (compared to 60% of the controls) carry a combi- nation of these DQAl and DQBl alleles either in cis or in trans position, i.e. they may have DQaP heterodimers with similar peptide binding prop- erties (3). |
