  • WHIM Syndrome: from Pathogenesis Towards Personalized Medicine and Cure
    Journal of Clinical Immunology (2019) 39:532–556 https://doi.org/10.1007/s10875-019-00665-w CME REVIEW WHIM Syndrome: from Pathogenesis Towards Personalized Medicine and Cure Lauren E. Heusinkveld1,2 & Shamik Majumdar1 & Ji-Liang Gao1 & David H. McDermott1 & Philip M. Murphy1 Received: 22 April 2019 /Accepted: 26 June 2019 /Published online: 16 July 2019 # This is a U.S. Government work and not under copyright protection in the US; foreign copyright protection may apply 2019 Abstract WHIM syndrome is a rare combined primary immunodeficiency disease named by acronym for the diagnostic tetrad of warts, hypogammaglobulinemia, infections, and myelokathexis. Myelokathexis is a unique form of non-cyclic severe congenital neutropenia caused by accumulation of mature and degenerating neutrophils in the bone marrow; monocytopenia and lympho- penia, especially B lymphopenia, also commonly occur. WHIM syndrome is usually caused by autosomal dominant mutations in the G protein-coupled chemokine receptor CXCR4 that impair desensitization, resulting in enhanced and prolonged G protein- and β-arrestin-dependent responses. Accordingly, CXCR4 antagonists have shown promise as mechanism-based treatments in phase 1 clinical trials. This review is based on analysis of all 105 published cases of WHIM syndrome and covers current concepts, recent advances, unresolved enigmas and controversies, and promising future research directions.

Methods: Conducting extensive review of literature related to osteopetrosis patients with schizophre- nia, summing common disease genes and diagnosis of osteopetrosis in association with schizophrenia. Results and Conclusion: Osteopetrosis is a rare inherited metabolic bone disease, with 12 kinds of common disease genes. In particular, mutations at 16p13.3 are closely related to schizophrenia. In recent years, molecular studies have identified three genes on chromosome 16 closely associated with schizophrenia, located at 16p13.3, 16p11.2, 16p13.11. Thus osteopetrosis and schizophrenia may not be two independent diseases, and understanding their relationship may help to identify schizophrenia at an earlier stage in osteopetrosis patients with mutations of chro- mosome 16. Conversely, patients with a family history of schizophrenia may be at increased risk for developing osteopetrosis. Keywords: Osteopetrosis, schizophrenia, pathogenic gene, diagnosis Introduction the possibility of such an association in the present case study of a patient diagnosed with Osteopetrosis is an extremely rare hereditary both disorders and possessing common identi- metabolic bone disease characterized by a fied genetic mutations.
