Abstract: Immuno-actinopathies are hereditary diseases characterized by immunodeficiency and immune dysregulation due to the mutations in single genes which are regulating actin remodeling. Mutations in actin-related regulatory genes can lead to functional defects in actin activation, extension, branching, transcription and others. The mutations also affect the cytoskeleton and pseudopod formation; then they further affect the functions of immune cell, resulting in cell deformation, motility, phagocytosis, and adhesion. The clinical manifestations vary, including infection, autoimmunity, autoinflammatory, and susceptibility to tumors, making the detection and diagnosis difficult. The pathogenic mechanisms of some of the related diseases have been preliminarily elucidated. Future research will focus on the identification of new immunoactinopathy-caused genes and its mechanism, discovery of new precision therapeutic target, development of drugs, improvement of hematopoietic stem cell transplantation strategies, and discovery of new gene therapy. Immuno-actinopathies have a low incidence rate with diversified clinical manifestations so that they are easy to be misdiagnosed and missed. This article reviews the pathogenic gene defects of actinopathies and their clinical manifestations in detail that are valuable to clinical reference.
