obsolete blood group, gerbich system https://github.com/monarch-initiative/mondo/issues/4521 https://www.malacards.org/card/blood_group_gerbich_system true MONDO:0044284 GE OBSOLETE. The Gerbich blood group system contains 6 high-prevalence and 5 low-prevalence antigens that are expressed on glycophorin C (GPC), glycophorin D (GPD), or both GPC and GPD. GPC and GPD, which contribute stability to the red blood cell membrane, are encoded by the same gene, GYPC, through the use of alternative translational start sites. Deficiency of GPC and GPD is associated with hereditary elliptocytosis, and Gerbich antigens act as receptors for the malarial parasite Plasmodium falciparum (see OMIM:611162). The Gerbich antibodies anti-Ge2 and anti-Ge3 have caused hemolytic transfusion reactions, and anti-Ge3 has produced hemolytic disease of the fetus and newborn (review by {12:Walker and Reid, 2010}). OMIM:616089 blood group, Gerbich Obsoleted as it represents a trait or is a legacy entry
