HLA-DRB4 details
What HLA-DRB4 shows
HLA-DRB4 is one of several related genes in the HLA-DR region, relevant to tissue typing for organ and stem cell transplant matching and studied for associations with certain autoimmune conditions. Like the other HLA-DR genes, it's typically assessed as part of a broader HLA typing panel used mainly for transplant compatibility testing.
Tests that include HLA-DRB4
This test identifies a patient's HLA DRB1/3/4/5 and DQB1 genotypes.
Biomarkers
- HLA-DQB1 A genetic marker used in celiac disease risk assessment and in tissue-typing for organ/stem cell transplant matching.
- HLA-DRB1 A genetic marker used in tissue typing for transplant matching and studied in relation to autoimmune disease risk, including rheumatoid arthritis.
- HLA-DRB3 A genetic marker used in HLA tissue typing, relevant to transplant matching and certain autoimmune and neurological associations.
- HLA-DRB4 A genetic marker used in HLA tissue typing, relevant to transplant matching and certain autoimmune associations.
- HLA-DRB5 A genetic marker used in HLA tissue typing, relevant to transplant matching and certain autoimmune associations.
