It is caused by a mutation in the ELANE gene on chromosome 19.
Patients present with cyclic neutropenia starting in childhood with a cycle of approximately 21 days. Recurrent infections with fever are also common features.[15]
The mainstay of treatment is giving granulocyte-colony stimulating factor (GCSF or CSF3)[16]

Leukocyte adhesion deficiency
Autosomal recessive transmission.
It results from a deficiency of the beta-2 integrin subunit of the leukocyte cell adhesion molecule, which results in poor neutrophil chemotaxis and phagocytosis.
