BACKGROUND: The molecular cause of severe congenital neutropenia (SCN) is unknown in 30% to 50% of patients. SEC61A1 encodes the α-subunit of the Sec61 complex, which governs endoplasmic reticulum protein transport and passive calcium leakage. Recently, mutations in SEC61A1 were reported to be pathogenic in common variable immunodeficiency and glom...

Patients with the pre-leukemia bone marrow failure syndrome called severe congenital neutropenia (CN) have an approximately 15% risk of developing acute myeloid leukemia (AML; called here CN/AML). Most CN/AML patients co-acquire CSF3R and RUNX1 mutations, which play cooperative roles in the development of AML. To establish an in vitro model of leuk...

Severe congenital neutropenia caused by ELANE gene mutation is a rare disease. To date, only four families were reported with mosaicism. Here we examined the morphology and function of granulocytes isolated from two patients and their mosaic fathers. Analysis of granulocytes isolated from the fathers revealed no genetic mutations. DNA extracted fro...

PurposeWe report normal neutrophil count in a mother, who carries the same ELANE mutation as her daughter with severe congenital neutropenia. We hypothesized that the mother possessed wild- and mutant-type clones and the wild-type clones could generate neutrophils, whereas the mutant clones could not.MethodsWe confirmed mutant variant ratio by sequ...

The development of a myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) in patients with congenital neutropenia is now the major cause of mortality. Treatment options are limited and there are no effective prevention strategies. This review focuses on mechanisms of leukemic transformation in severe congenital neutropenia (SCN) and Shwac...

Splicing is a ubiquitous process in eukaryotic cells, long recognised as contributing to diversity of the transcriptome. More specifically, splicing fine-tunes the transcriptome output for highly individual outcomes at different stages of cell development, in specific timeframes, which when perturbed result in significant human diseases. Granulopoi...

PurposeHomozygous mutations in the HAX1 gene cause an autosomal recessive form of severe congenital neutropenia (SCN). There are limited data on cases of gonadal insufficiency that involve the HAX1 gene mutation. We aimed to evaluate the pubertal development and gonadal functions of our patients with a p.Trp44X mutation in the HAX1 gene.MethodPuber...

Severe congenital neutropenia (CN) is a bone marrow failure syndrome characterized by an absolute neutrophil count (ANC) below 500 cells/μL and recurrent, life-threatening bacterial infections. Treatment with granulocyte colony-stimulating factor (G-CSF) increases the ANC in the majority of CN patients. In contrary, granulocyte-monocyte colony-stim...
