Inherited bone marrow failure syndromes: considerations pre- and posttransplant.

Inherited bone marrow failure syndromes: considerations pre- and posttransplant. Hematology Am Soc Hematol Educ Program. 2017 Dec 08;2017(1):88-95 Authors: Alter BP Abstract Patients with inherited bone marrow failure syndromes are usually identified when they develop hematologic complications such as severe bone marrow failure, myelodysplastic syndrome, or acute myeloid leukemia. They often have specific birth defects or other physical abnormalities that suggest a syndrome, and sequencing of specific genes or next-generation sequencing can determine or confirm the particular syndrome. The 4 most frequent syndromes are Fanconi anemia, dyskeratosis congenita, Diamond Blackfan anemia, and Shwachman Diamond syndrome. This review discusses the major complications that develop as the patients with these syndromes age, as well as additional late effects following hematopoietic stem cell transplantation. The most common complications are iron overload in transfused patients and syndrome-specific malignancies in untransplanted patients, which may occur earlier and with higher risks in those who have received transplants.

DiNardoAbstractMyelodysplastic syndromes and acute myeloid leukemia are sporadic for the majority of cases affecting the elderly population. Inherited cases, however, do occur. Genetic predispositions to myeloid malignancies can be classified into three categories: familial cancer syndromes associated with increased risk of various malignancies including myelodysplasia and acute myeloid leukemia such as Li-Fraumeni syndrome and constitutional mismatch repair deficiency (CMMRD); germline mu...

Conclusion: This is the largest series of subtyped Japanese FA patients to date and the results would be useful for future clinical management. To provide molecular diagnosis for FA in Japan, we suggest to start with PCR-direct sequencing of the three common mutations (FANCA c.2546delC, FANCG c.307+1G>C and FANCG c.1066C>T) along with MLPA assay for FANCA. These analyses would enable the identification of about 50% of the mutant alleles. For the rest of the cases, WES or targeted-seq analysis should be useful, however, large deletions and aberrant splicing need to be kept in mind.DisclosuresTakaori-Kondo: Pfizer: Hon...

Conclusion: Along with growing recognition of the disease among physicians and establishment of mutation analysis system, newly diagnosed cases of SDS were accumulated constantly. SDS may be more common than previously thought in our country. Clinical characteristics are similar to those that were reported in previous studies. As shown in a recent study on a large MDS cohort from an international registry of HSCT, patients with SDS may develop AML in adulthood and have very poor prognosis. The SDS cohort in Japan may provide a platform to investigate clinical and genetic factors associated with severity and phenotypes of t...

Authors: West AH, Churpek JE Abstract Patients with inherited bone marrow failure syndromes (IBMFSs) classically present with specific patterns of cytopenias along with congenital anomalies and/or other physical features that are often recognizable early in life. However, increasing application of genomic sequencing and clinical awareness of subtle disease presentations have led to the recognition of IBMFS in pediatric and adult populations more frequently than previously realized, such as those with early onset myelodysplastic syndrome (MDS). Given the well-defined differences in clinical management needs and outc...

Publication date: September–December 2014 Source:Best Practice & Research Clinical Haematology, Volume 27, Issues 3–4 Author(s): Blanche P. Alter Fanconi anemia (FA) is a rare autosomal recessive cancer-prone inherited bone marrow failure syndrome, due to mutations in 16 genes, whose protein products collaborate in a DNA repair pathway. The major complications are aplastic anemia, acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), and specific solid tumors. A severe subset, due to mutations in FANCD1/BRCA2, has a cumulative incidence of cancer of 97% by age 7 years; the cancers are AML, brain ...

Abstract Inherited bone marrow failure (IBMF) syndromes are a heterogeneous group of rare hematological disorders characterized by the impairment of hematopoiesis, which harbor specific clinical presentations and pathogenic mechanisms. Some of these syndromes may progress through clonal evolution, myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). Most prominent are failures of DNA repair such as Fanconi Anemia and much rarer failure of ribosomal apparatus, e.g., Diamond Blackfan Anemia or of telomere elongation such as dyskeratosis congenita. In these congenital disorders, hematopoietic stem cell tr...
