Accordingly, the European Hematology Association and the EuNet-INNOCHRON COST Action working group have recommended the term “ACKR1/DARC-associated neutropenia (ADAN)” instead of ethnic neutropenia to reflect a genetic rather than racial basis, while the American Society of Hematology utilizes “Duffy-null associated neutrophil count.” [11]. Here, ACKR1 is linked to Decreased total neutrophil count.
