Antibodies against high frequency Gerbich 2 antigen (anti–Ge2): A real challenge in cross matching lab
نویسنده
چکیده
Transfusion management of patients' alloimmunized against high-prevalence erythrocyte antigens is often problematic in emergency situations. Gerbich (Ge) is very common blood group system and Gerbich-2 (Ge-2) antigen present in high frequency and outside Papua New Guinea population, Ge-2 negative population almost nil. To manage such kind of problems with real emergencies, implementation of rare donor registry program, cryopreservation of red cells of rare donors and biological cross matching to assess significance of these antibodies is warranted.

Genetic background of the rare Yus and Gerbich blood group phenotypes: homologous regions of the GYPC gene contribute to deletion alleles.
The GYPC gene encodes the glycophorins C and D. The two moieties express 12 known antigens of the Gerbich blood group system and functionally stabilize red blood cell membranes through their intracellular interaction with protein 4.1 and p55. Three GYPC exon deletions are responsible for the lack of the high-frequency antigens Ge2 (Yus type, exon 2 deletion), Ge2 and Ge3 (Gerbich type, exon 3 d...
متن کاملThe First Korean Case Report of Anti-Gerbich
In this study, we report the first Korean case of an anti-Gerbich (Ge) alloantibody to a high-incidence antigen that belongs to the Ge blood group system. The alloantibody was detected in a middle-aged Korean woman who did not have a history of transfusion. Her blood type was B+, and findings from the antibody screening test revealed 1+ reactivity in all panels except the autocontrol. The cross...
متن کامل(De)Toxifying Enzyme Microsomal Epoxide Hydrolase Identification of the Putative Brain Tumor Antigen BF7/GE2 as Updated Version
Malignant gliomas are the main cause of death from primary brain tumors. Despite surgery, radiation, and chemotherapy, patients have a median survival of less than a few years; therefore, it is clearly imperative to investigate new ways of treatment. The development of new therapeutic strategies for brain tumors is dependent on a better understanding of the differences between normal and tumora...

متن کاملRed Blood Cells Alloimmunization and Autoimmunization in Multi-transfused Thalassemia Patients in South of Iran
Background: Recurrent blood transfusion is a common treatment in patients with thalassemia. The development of antibodies against red blood cell (RBC) antigens complicates RBC cross-matching, enhances the in vivo destruction of transfused cells, accelerates tissue iron overloading, delays the provision of safe transfusion, and reduces health-related quality of life. Materials and Methods: In t...
