Abstract Clozapine is the most effective therapy for treatment-resistant schizophrenia, although it can cause neutropenia. In many countries, neutrophil count monitoring is mandatory for people taking clozapine, who must remain above a minimum threshold to start and continue treatment. Some people have low neutrophil counts without increased infection risk, caused by a homozygous variant in ACKR1 and termed ACKR1/DARC-associated neutropenia (ADAN).
