Clinical evaluation, bone marrow biopsy and/or genetic testing can help inform a WHIM syndrome diagnosis.1

When should WHIM syndrome be suspected?

WHIM syndrome should be suspected in any case of unexplained chronic neutropenia with lymphopenia, monocytopenia, or both.2 However, neutropenia may be difficult to detect due to elevated neutrophil counts that are present during acute infections.3

Genetic testing for CXCR4 pathogenic variants, bone marrow biopsy to detect myelokathexis, or both may be instructive and help inform a clinical diagnosis.1

How is WHIM syndrome managed?

Interventions for patients with WHIM syndrome often include symptomatic management. Early diagnosis and intervention may play an important role in reducing the risk of potential long-term complications.2,6
