Neutropenia, Lethal Congenital, With Eosinophilia

Andrews et al. (1960) described 2 affected sibs. The parents were not known to be related. It is not entirely certain that this is an entity separate from that listed as agranulocytosis (202700). It is possible that some cases of neonatal neutropenia are due to fetomaternal immunization involving neutrophil-specific antigens (Lalezari and Radel, 1974).
