Genotyping of human neutrophil antigen‐5a (Ond)

summary . Antibodies to human neutrophil alloantigens (HNA) can cause immune‐mediated neutropenias and transfusion complications. The diagnosis of antibodies to the HNA‐5a (Ond) isoform of the α L β 2 integrin is hampered by the lack of reliable methods for HNA‐5a antigen typing. We have devised a polymerase chain reaction sequence‐specific primer method (PCR‐SSP) and used it to determine the HNA‐5a gene frequencies in 320 individuals from...
