Immunodeficiency, centromeric instability and facial anomalies syndrome 2 (ICF2) is a rare autosomal recessive primary immunodeficiency disorder. So far, 27 patients have been reported. Here, we present three siblings with ICF2 due to a homozygous ZBTB24 gene mutation (c.1222 T>G, p. (Cys408Gly)). Immune deficiency in these patients ranged from late-onset combined immunodeficiency (CID) with severe respiratory tract infections and recurrent shingles to asymptomatic selective antibody deficiency. Evident clinical heterogeneity manifested despite a common genetic background, suggesting the pathogenic relevance of epigenetic modification. Immunological follow-up reveals a previously unidentified gradual depletion of B and CD4+ T cells in all three presented patients with transition of a common variable immunodeficiency (CVID)-like disease to late-onset-CID in one of them. Considering all previously published cases with ICF2, we identify inadequate antibody responses to vaccines and reduction in CD27+ memory B cells as prevalent immunological traits. High mortality among ICF2 patients (20%) together with the progressive course of immunodeficiency suggest that hematopoietic stem cell transplantation (HSCT) should be considered as a treatment option in due time.

Background: Immunodeficiency, centromeric instability and facial dysmorphism )ICF) syndrome is a rare autosomal recessive immune disorder presenting with hypogammaglobulinemia, developmental delay, and facial anomalies. The ICF type 1, type 2, type 3 and type 4 are characterized by mutations in DNMT3B, ZBTB24, CDCA7 or HELLS gene, respectively. This study aimed to present a comprehensive description of the clinical, immunologic and genetic features of patients with ICF syndrome. Methods: PubMed, Web of Science, and Scopus were searched systemically to find eligible studies. Results: Forty-eight studies with 118 ICF patients who met the inclusion criteria were included in our study. Among these patients, 60% reported with ICF-1, 30% with ICF-2, 4% with ICF-3, and 6% with ICF-4. The four most common symptoms reported in patients with ICF syndrome were: delay in motor development, low birth weight, chronic infections, and diarrhea. Intellectual disability and preterm birth among patients with ICF-2 and failure to thrive, sepsis and fungal infections among patients with ICF-1 were also more frequent. Moreover, the median levels of all three immunoglobulins (IgA, IgG, IgM) were markedly reduced within four types of ICF syndrome. Conclusion: The frequency of diagnosed patients with ICF syndrome has increased. Early diagnosis of ICF is important since immunoglobulin supplementation or allogeneic stem cell transplantation can improve the disease-free survival rate.
