Hematopoiesis post anti-CD117 monoclonal antibody treatment in wild-type and Fanconi anemia settings
Haematologica. 2024 Apr 4. doi: 10.3324/haematol.2023.284275. Online ahead of print.ABSTRACTAnti-CD117 monoclonal antibody (mAb) agents have emerged as exciting alternative conditioning strategies to traditional genotoxic irradiation or chemotherapy conditioning for both allogeneic and autologous gene-modified hematopoietic stem cell transplantation. Further, these agents are concurrently being explored in the treatment of mast cell disorders. Despite promising results in animal models and more recently in patients, the short-term and long-term effects of these treatments have not been fully explored. We conducted rigorous...

Key Clinical MessageFanconi anemia with Mitomycin C sensitivity is a rare, complex hematological condition. Our case study emphasizes the significance of early diagnosis, appropriate genetic testing, and cautious use of chemotherapeutic agents.AbstractFanconi anemia (FA) is a rare genetic disorder characterized by bone marrow failure, congenital anomalies, and predisposition to cancer. Here, we present the case of a 6-year-old boy with a known diagnosis of Fanconi anemia who exhibited sensitivity to Mitomycin C. The patient had a history of recurrent blood transfusions due to anemia and was referred to our institution foll...

SMARCAL1 ubiquitylation controls its association with RPA-coated ssDNA and promotes replication fork stability
by Ma ïlyn Yates, Isabelle Marois, Edlie St-Hilaire, Daryl A. Ronato, Billel Djerir, Chloé Brochu, Théo Morin, Ian Hammond-Martel, Sari Gezzar-Dandashi, Lisa Casimir, Elliot Drobetsky, Laurent Cappadocia, Jean-Yves Masson, Hugo Wurtele, Alexandre Maréchal Impediments in replication fork progression cause genomic instability, mutagenesis, and severe pathologies. At stalled forks, RPA-coated single-stranded DNA (ssDNA) activates the ATR kinase and directs fork remodeling, 2 key early events of the replication stress response. RFWD3, a recently described Fanconi anemia (FA) ubiquitin ligase, associates with RPA and promo...

Umbilical Cord Blood Transplantation for Fanconi Anemia with a special focus on late complications: a Study on Behalf of Eurocord and SAAWP-EBMT
Fanconi anemia (FA) is an inherited bone marrow failure syndrome characterized by a broad spectrum of morphological malformations, progressive trilineage cytopenia, multisystem defects and increased predisposition to hematological malignancies and solid tumors [1 –3]. The Fanconi core complex and its associated protein complexes are required to ensure timely DNA repair. The risk for these major events is age dependent. Approximately 75% of FA patients have birth defects. Severe bone marrow failure (BMF) develops in 70% of patients by the age of 50 years, t ypically peaking during childhood at a median age of 7 years. (So...

Identifying an AML Prognostic Model Using 10 Marker Genes from Single-Cell Transcriptome and Bulk Transcriptome Analysis
The objective of this study is to examine the involvement of the FANC core complex in BMF and ascertain nucleolar homeostasis-related genes by conducting transcriptome analysis on primary hematopoietic stem cells obtained from FA patients with FANCA and FANCC variants. In the present study, we analyzed scRNA-seq data obtained from both healthy donors and individuals diagnosed with FA in order to investigate the phenomenon of cell-cell communication. Through the implementation of trajectory analysis, the differentiation pathways of several progenitor cell types, such as HSC cells transitioning into LMPP, N, M, B-prog, and E...

Newly Recognized Genetic Tumor Syndromes of the CNS in the 5th WHO Classification: Imaging Overview with Genetic Updates [BRAIN TUMOR IMAGING]
SUMMARY: The nervous system is commonly involved in a wide range of genetic tumor-predisposition syndromes. The classification of genetic tumor syndromes has evolved during the past years; however, it has now become clear that these syndromes can be categorized into a relatively small number of major mechanisms, which form the basis of the new 5th edition of the World Health Organization book (beta online version) on genetic tumor syndromes. For the first time, the World Health Organization has also included a separate chapter on genetic tumor syndromes in the latest edition of all the multisystem tumor series, including t...

Long-Term Follow-up of Outcomes of Hematopoietic Stem Cell Transplantation for Patients with Fanconi Anemia: A Single Center Retrospective Review
Fanconi anemia (FA) is an inherited bone marrow failure syndrome caused by defects in DNA repair. Patients often require hematopoietic stem cell transplantation (HSCT) to cure their severe bone marrow failure. Owing to the defects in DNA repair, patients with Fanconi anemia have significant morbidity with myeloablative conditioning prior to HSCT. Previous studies have reported good outcomes with reduced intensity conditioning (RIC) prior to HSCT for patients with FA. There are limited studies that compare outcomes between matched related donors and alternative donors. (Source: Biology of Blood and Marrow Transplantation)

Longitudinal Bone Health in Patients with Fanconi Anemia and Other Major Inherited Bone Marrow Failure Syndromes
Longitudinal bone health outcomes in patients with major inherited bone marrow failure syndromes (IBMFS) are not well characterized. We hypothesized that fracture incidence was high in patients with Fanconi Anemia, Dyskeratosis Congenita (DC), Shwachman-Diamond Syndrome (SDS) and Diamond-Blackfan Anemia (DBA). We aimed to compare these outcomes in patients who were and were not treated with hematopoietic stem cell transplant (HSCT). (Source: Biology of Blood and Marrow Transplantation)

Monoallelic Germline Pathogenic Variants in DNA Damage Repair Genes and Their Impact on Post-Hematopoietic Cell Transplantation Outcomes in Severe Aplastic Anemia
Recipients of HCT are under significant stressors that may predispose them to DNA damage and unfavorable outcomes. Patients with inherited defects in DNA damage response or repair (DDRR), such as Fanconi anemia, need special conditioning regimens to minimize toxicity. HCT outcomes in patients carrying pathogenic or likely pathogenic (P/LP) variants in DDRR genes is unknown. (Source: Biology of Blood and Marrow Transplantation)
