HLA antigen DQB1*0602
The HLA DQB1*0602 antigen is a protein thatóbelongs to the group of human leukocyte antigens (HLA), whichóconstitute the human tissue compatibility system, responsible for recognition of one's own cellsórecords or tolerance of one's own cellsórecords and tissues. The test checks for the presence of this protein, whichóre likely to be associated with someósome autoimmune diseases.

HLA antigen DQB1*0602
Clinical significance
HLA - human leukocyte antigen. HLA antigens are found in rólous numbers on almost all of the bodyós nucleated cells. The immune response to these antigens is the primary cause of the occurrence of allograft rejection. The antigens of the HLA system are under the control of a complex of genesów located at several closely related loci, referred to as the major histocombatibility complex (MHC), whichós located on chromosome 6. The HLA system is a polymorphic system. There are two classes, HLA I and HLA II, within each there are several multi-allelic antigenic systems. In the HLA I class, the antigens of importance in transplantation are HLA-A, HLA-B, HLA-C. In HLA class II, HLA-DR, HLA-DQ and HLA-DP antigens with their 18 D HLA-DR, 9 HLA-DQ and 6 HLA-DP antigenic specificities play roles in transplantation. HLA testing has applications beyond tissue compatibility evaluation. The most important function of MHC molecules is to bind and present antigensów to T lymphocytes. Most autoimmune diseases have a multigene basis, especiallyós HLA class II genes. The HLA-DQB1*0602 antigen correlates with the risk of insulin-dependent diabetes mellitus.
