HLA region of Chromosome 6. The human leukocyte antigen (HLA) system is a complex of genes on chromosome 6 in humans that encode cell-surface proteins responsible for regulation of the immune system. [1] The HLA system is also known as the human version of the major histocompatibility complex (MHC) found in many animals. [2]
[10] [11] HPA-1a is present in 98% of the population of the United States, suggesting that approximately 2% of women who are HPA-1a negative may be at risk for NAIT during pregnancy. [ 1 ] [ 12 ] Of course, the antigen expression of the father must also be taken into account - in most cases the father is HPA -1a/1a or 1a/1b and the mother is ...
Hemolytic disease of the fetus and newborn is similar to a transfusion reaction in that the mother's antibodies cannot tolerate the fetus's antigens, which happens when the immune tolerance of pregnancy is impaired. In many instances the maternal immune system attacks the fetal blood cells, resulting in fetal anemia.
In any pregnancy, the maternal KIR genotype could be AA (no activating KIRs), AB, or BB (1–10 activating KIRs) and the HLA-C ligands for KIRs are divided into two groups: HLA-C1 and HLA-C2. Studies have shown that there is a bad compatibility between specifically maternal KIR AA and fetal HLA-C2 which leads to recurrent miscarriage ...
A panel-reactive antibody (PRA) is a group of antibodies in a test serum that are reactive against any of several known specific antigens in a panel of test leukocytes or purified HLA antigens from cells. It is an immunologic metric routinely performed by clinical laboratories on the blood of people awaiting organ transplantation. [1]
Antiphospholipid syndrome is known for causing arterial or venous blood clots, in any organ system, and pregnancy-related complications.While blood clots and pregnancy complications are the most common and diagnostic symptoms associated with APS, other organs and body parts may be affected like platelet levels, heart, kidneys, brain, and skin.
HLA-DQ8 (DQ8) is a human leukocyte antigen serotype within the HLA-DQ (DQ) serotype group. DQ8 is a split antigen of the DQ3 broad antigen. DQ8 is determined by the antibody recognition of β 8 and this generally detects the gene product of DQB1*0302. DQ8 is commonly linked to autoimmune disease in the human population.
HLA(haplotypes) In terms of genetics one finds that autoimmune polyendocrine syndrome type 2 has an autosomal dominant pattern of inheritance, with an incomplete penetrance. [ 7 ] [ 8 ] Furthermore, the human leukocyte antigen involved in this condition are HLA-DQ2(DR3 (DQB*0201)) and HLA-DQ8(DR4 (DQB1*0302)), [ 9 ] genetically speaking , which ...
