A form of bone marrow failure syndrome, a heterogeneous group of life-threatening disorders characterized by hematopoietic defects in association with a range of variable extra-hematopoietic manifestations. BMFS4 is characterized by early-onset anemia, leukopenia, decreased B cells, and developmental aberrations including facial dysmorphism, mild skeletal anomalies, and neurodevelopmental delay. BMFS4 inheritance is autosomal recessive.

Immunoskeletal dysplasia with neurodevelopmental abnormalities
An autosomal recessive disorder characterized by variable skeletal abnormalities and neurodevelopmental defects. Neurologic manifestations include intellectual disability and motor delay. Some patients manifest hypotonia and seizures. Skeletal features include disproportionate short stature, cervical malformations, epiphyseal and metaphyseal dysplasia, and rarely premature craniosynostosis with progressive microcephaly. Severe combined immunodeficiency with a complete absence of T cells is observed in some patients.
ATP-dependent annealing helicase that binds selectively to fork DNA relative to ssDNA or dsDNA and catalyzes the rewinding of the stably unwound DNA. Rewinds single-stranded DNA bubbles that are stably bound by replication protein A (RPA). Acts throughout the genome to reanneal stably unwound DNA, performing the opposite reaction of many enzymes, such as helicases and polymerases, that unwind DNA. May play an important role in DNA damage response by acting at stalled replication forks

Case Report: Post-transplant lymphoproliferative disorder after kidney transplantation in a child with schimke immuno-osseous dysplasia.
With the inherent T-cell immunodeficiency of Schimke immune-osseous dysplasia (SIOD), the management of immunosuppressive therapy after transplantation and life-threatening infections remains a challenge. Here, we present a case of a child with SIOD who developed early-onset Epstein-Barr virus (EBV)-associated post-transplant lymphoproliferative disorder (PTLD) after kidney transplantation. PTLD frequently involves the gastrointestinal tract and solid allografts, while this case also involved the lungs, which is extremely rare. This case underscores the importance of considering PTLD in recipients with immunodeficiency, long-term immunosuppressive therapy, and EBV seronegativity. It also suggests low-dose immunotherapy and hematopoietic stem-cell transplantation for patients with SIOD.
Genetic and Clinical Features of Schimke Immuno-Osseous Dysplasia: Single-Centre Retrospective Study of 21 Unrelated Paediatric Patients over a Period of 20 Years.
Schimke immuno-osseous dysplasia (SIOD) is a hereditary autosomal-recessive multi-system disorder with early mortality. It has variable clinical presentations, mainly characterised by disproportional short stature, steroid-resistant nephrotic syndrome, spondyloepiphyseal dysplasia, and T-cell immunodeficiency. In the majority of cases, SIOD is caused by pathogenic sequence variants (PSVs) in the SMARCAL1 gene that encodes protein involved in chromatin remodelling. SIOD is an ultra-rare condition, with an incidence of ~1 per 1-3 million live births; data on its genetic and clinical features are scarce. We conducted a retrospective study of 21 paediatric patients with SIOD diagnosed in our centre during the years 2003-2023. The most common extra-renal clinical features were short stature, osseous dysplasia, multiple stigmas, and leukopenia. Proteinuria of varying severity was observed in 16 cases. The five-year overall survival rate (OS) was 89% (95% CI 77-100%), and the ten-year OS was 10%. Next-generation sequencing (NGS) revealed the following PSVs in SMARCAL1 in 19 patients: c.355_500del, c.2542G>T, c.2290C>T, c.2562del, c.2533_2534del, c.1582A>C, c.1933C>T, c.1010T>C, c.1736C>T, c.2070dup, c.2551A>T, c.2149_2150dup, c.939delC, and c.1451T>A; the most common was c.2542G>T, resulting in premature translation termination (p.E848*), and it was found in 14 patients either in a homozygous (four patients) or compound-heterozygous (10 patients) state. According to microsatellite analysis, it is a "founder mutation" in Russia.

Successful Use of Haploidentical HSCT in a Child With Schimke Immuno-Osseous Dysplasia Who Developed PTLD After Kidney Transplantation.
Schimke Immuno-Osseous Dysplasia Is a Rare Autosomal Recessive Multisystem Disorder Caused by Biallelic Pathogenic Variants in the SMARCAL1 Gene, Which Encodes a DNA Annealing Helicase Essential for Replication Fork Stability and Genomic Maintenance. Loss of SMARCAL1 Function Leads to Genomic Instability, Resulting in a Characteristic Clinical Triad of Disproportionate Short Stature, Steroid-Resistant Nephrotic Syndrome and Immunodeficiency. Kidney Transplantation Is the Standard Treatment for End-Stage Renal Disease in Schimke Immuno-Osseous Dysplasia. However, the Underlying Genomic Fragility and Immunodeficiency Heighten the Risk of Post-Transplant Complications, Particularly Epstein-Barr Virus-Associated Post-Transplant Lymphoproliferative Disorder. We Report the Case of a 7-Year-Old Girl With Genetically Confirmed Schimke Immuno-Osseous Dysplasia Who Developed Epstein-Barr Virus-Positive Diffuse Large B-Cell Lymphoma Eight Months Following Maternal Kidney Transplantation, Despite Reduced-Intensity Immunosuppression. Rituximab Therapy Resulted in Complete Remission, but Required the Withdrawal of all Immunosuppressive Agents, Thereby Posing a Risk of Kidney Graft Loss. In the Context of Primary Immunodeficiency and the Development of Post-Transplant Lymphoproliferative Disorder in Such a Setting, the Patient Subsequently Underwent Haploidentical Hematopoietic Stem Cell Transplantation From the Mother, Using an αβ T-Cell-Depleted Graft and a Nephrotoxicity-Sparing Conditioning Regimen. Full Donor Chimerism Was Achieved by Day 28. Immune Reconstitution Occurred Within One Year. At 27 Months After Hematopoietic Stem Cell Transplantation She Remains in Remission With Preserved Kidney Function and no Ongoing Immunosuppression. This Case Highlights the Feasibility of Haploidentical Hematopoietic Stem Cell Transplantation as a Curative Salvage Strategy for Immunosuppression-Free Survival After Kidney Transplantation in Patients With Schimke Immuno-Osseous Dysplasia.
