MECANISMO DE DOENÇA

Anemia, sideroblastic, 1

A form of sideroblastic anemia that shows a variable hematologic response to pharmacologic doses of pyridoxine. Sideroblastic anemia is characterized by anemia of varying severity, hypochromic peripheral erythrocytes, systemic iron overload secondary to chronic ineffective erythropoiesis, and the presence of bone marrow ringed sideroblasts. Sideroblasts are characterized by iron-loaded mitochondria clustered around the nucleus.

X-Linked Sideroblastic Anemia Induced by a Novel ALAS2 Nonsense Mutation: A Case Report and Literature Review.

Annals of clinical and laboratory science2025 Sep

To clarify the clinical manifestations of X-linked sideroblastic anemia (XLSA) and the mutational profiles of the aminolevulinate synthase 2 (ALAS2) gene, thereby optimizing treatment and prognosis. The proband, a 16-year-old male student, presented with microcytic hypochromic anemia, with hemoglobin (Hb) 55 g/L, red cell distribution width (RDW) 22.5%, mean corpuscular hemoglobin concentration (MCHC) 314 g/L, mean corpuscular hemoglobin (MCH) 23.9 pg, and mean corpuscular volume (MCV) 76.1 fL. Next-generation sequencing followed by Sanger sequencing of his family identified a de novo heterozygous nonsense mutation in ALAS2 (c.224C>A); this identification led to the final diagnosis of XLSA with a novel ALAS2 mutation. Incorporating genetic analyses into diagnostic algorithms can improve the precision of XLSA diagnosis and support personalized treatment strategies for patients and families. Our findings expand the mutational spectrum of ALAS2 and highlight that integrating next-generation sequencing (NGS) with Sanger validation into diagnostic workflows can significantly improve the diagnostic accuracy of XLSA.

X-linked sideroblastic anemia in females.

Blood2025 Apr 03

X-linked sideroblastic anemia (XLSA) in female carriers of 5-aminolevulinic acid synthase 2 mutations is not uncommon. We describe unique features and genotype/phenotype correlations in females with XLSA and evaluate the contributions of X-chromosome skewing and clonal hematopoiesis, emphasizing the importance of distinguishing it from myelodysplastic syndromes with ring sideroblasts.

SLC25A38 is required for mitochondrial pyridoxal 5'-phosphate (PLP) accumulation.

Nature communications2025 Jan 24

Many essential proteins require pyridoxal 5'-phosphate, the active form of vitamin B6, as a cofactor for their activity. These include enzymes important for amino acid metabolism, one-carbon metabolism, polyamine synthesis, erythropoiesis, and neurotransmitter metabolism. A third of all mammalian pyridoxal 5'-phosphate-dependent enzymes are localized in the mitochondria; however, the molecular machinery involved in the regulation of mitochondrial pyridoxal 5'-phosphate levels in mammals remains unknown. In this study, we used a genome-wide CRISPR interference screen in erythroleukemia cells and organellar metabolomics to identify the mitochondrial inner membrane protein SLC25A38 as a regulator of mitochondrial pyridoxal 5'-phosphate. Loss of SLC25A38 causes depletion of mitochondrial, but not cellular, pyridoxal 5'-phosphate, and impairs cellular proliferation under both physiological and low vitamin B6 conditions. Metabolic changes associated with SLC25A38 loss suggest impaired mitochondrial pyridoxal 5'-phosphate-dependent enzymatic reactions, including serine to glycine conversion catalyzed by serine hydroxymethyltransferase-2 as well as ornithine aminotransferase. The proliferation defect of SLC25A38-null K562 cells in physiological and low vitamin B6 media can be explained by the loss of serine hydroxymethyltransferase-2-dependent production of one-carbon units and downstream de novo nucleotide synthesis. Our work points to a role for SLC25A38 in mitochondrial pyridoxal 5'-phosphate accumulation and provides insights into the pathology of congenital sideroblastic anemia.

An erythroid-specific lentiviral vector improves anemia and iron metabolism in a new model of XLSA.

Blood2025 Jan 02

X-linked sideroblastic anemia (XLSA) is a congenital anemia caused by mutations in ALAS2, a gene responsible for heme synthesis. Treatments are limited to pyridoxine supplements and blood transfusions, offering no definitive cure except for allogeneic hematopoietic stem cell transplantation, only accessible to a subset of patients. The absence of a suitable animal model has hindered the development of gene therapy research for this disease. We engineered a conditional Alas2-knockout (KO) mouse model using tamoxifen administration or treatment with lipid nanoparticles carrying Cre-mRNA and conjugated to an anti-CD117 antibody. Alas2-KOBM animals displayed a severe anemic phenotype characterized by ineffective erythropoiesis (IE), leading to low numbers of red blood cells, hemoglobin, and hematocrit. In particular, erythropoiesis in these animals showed expansion of polychromatic erythroid cells, characterized by reduced oxidative phosphorylation, mitochondria's function, and activity of key tricarboxylic acid cycle enzymes. In contrast, glycolysis was increased in the unsuccessful attempt to extend cell survival despite mitochondrial dysfunction. The IE was associated with marked splenomegaly and low hepcidin levels, leading to iron accumulation in the liver, spleen, and bone marrow and the formation of ring sideroblasts. To investigate the potential of a gene therapy approach for XLSA, we developed a lentiviral vector (X-ALAS2-LV) to direct ALAS2 expression in erythroid cells. Infusion of bone marrow (BM) cells with 0.6 to 1.4 copies of the X-ALAS2-LV in Alas2-KOBM mice improved complete blood cell levels, tissue iron accumulation, and survival rates. These findings suggest our vector could be curative in patients with XLSA.
