Pelger-Huet anomaly

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

Pelger-Huet anomaly is a blood laminopathy associated with the lamin B receptor. It is characterized by a white blood cell type known as a neutrophil whose nucleus is hyposegmented.

It is a genetic disorder with an autosomal dominant inheritance pattern. Heterozygotes are clinical normal although their neutrophils may be mistaken for immature cells which may cause mistreatment in a clinical setting. Homozygotes tend to have neutrophils with rounded nuclei that do have some functional problems.
