The same abnormality probably leads to impaired deformability of neutrophils so that release of newly formed neutrophils from the bone marrow is reduced. Relative to the genetics and the possibility that these cases represent new dominant mutations, parental age data would be of interest. A bonus to all MIMmatch users is the option to sign up for updates on new gene-phenotype relationships.

We need long-term secure funding to provide you the information that you need at your fingertips. Miller knew of 4 other cases.


A severe neutropenia was found. Expert curators review the literature and organize it to facilitate your work.

Leukocyte phagocytosis and bactericidal activity were normal. Unfortunately, it is not free to produce.

While the OMIM database is open to the public, users seeking information about a lekkocyte medical or genetic condition are urged to consult with a qualified physician for diagnosis and for answers to personal questions.

Lazy leukocyte syndrome.

A characteristic abnormality of actin distribution in neutrophils was demonstrated. Both random mobility and chemotactic function were defective. Mobilization of leukocytes after exercise was defective. We are determined to keep this website freely accessible. Single cases were reported by Costanopoulos et al. Please consider making a donation now and again in the future.

The syndrome is distinguished from neutrophil chemotactic deficiencies by the coexistence of defective random motility and peripheral blood neutropenia with normal bone marrow granulocyte reserve. Bone marrow studies showed normal numbers of mature, morphologically normal neutrophils. Pathology of chemotaxis and random mobility. None is familial and no parental consanguinity lrukocyte known.

Clinical Synopsis Toggle Dropdown. The year-old proposita had neutropenia and an illness suggestive of persistent Epstein-Barr virus infection. A new disorder of neutrophil function. Autosomal dominant new mutations. Skin window mobilization test and chemotaxis were normal. Transient ‘lazy-leukocyte’ syndrome during infancy.

A poor neutrophil response was obtained upon stimulation with both epinephrine and endotoxin, as well as upon induced inflammation by the Rebuck skin window technique. OMIM is intended for use primarily by physicians and other professionals concerned with genetic disorders, by genetics researchers, and by advanced students in science and medicine.
