Summaries for Blood Group, Cromer System

OMIM : 58 The Cromer blood group system (CROM) consists of 12 high-prevalence and 3 low-prevalence antigens that reside on decay-accelerating factor (DAF, or CD55; 125240), a regulator of complement activation. Nearly all Cromer antigens result from SNPs in the DAF gene. The red blood cells (RBCs) of people with the Cromer-null phenotype, Inab, lack DAF but do not appear to show increased susceptibility to hemolysis. Antibodies to Cromer antigens are rarely encountered, although evidence suggests that the antibodies may cause accelerated destruction of transfused RBCs. Cromer system antibodies are not associated with hemolytic disease of the newborn, because placenta is a rich source of fetally derived DAF, which is thought to absorb the antibodies (review by Storry et al., 2010). The Inab phenotype is associated with CHAPLE syndrome (226300) in some individuals. (613793)
