HLA-DR14(DR14) is a HLA-DR serotype that recognizes the DRB1*1401 to *1408, *1410 to *1418, and other *14 gene products. DR14 serotype is a split antigen of the older HLA-DR6 serotype group which also contains the similar HLA-DR13 antigens.
Serotypes are unknown the following alleles: DRB1**1409, *1419 to *1462
DRB1*1402: juvenile rheumatoid arthritis, increased longevity in Okinawans.
DR*14:DQ5 haplotype: increased risk for non-AChR autoantibodies in myasthenia gravis.
HLA-DR13 is genetically linked to HLA-DR52 and HLA-DQ5 (HLA-DQ1) serotypes.
