Anemia sideroblástica
ORPHA:1047DOENÇA RARA

Um grupo de doenças raras e variadas da medula óssea, que podem ser hereditárias ou adquiridas. Elas podem aparecer sozinhas ou como parte de uma síndrome. Essas doenças são caracterizadas por uma produção reduzida de hemoglobina (a proteína que transporta oxigênio), causada por um uso inadequado do ferro no corpo, mesmo que os exames de sangue possam mostrar níveis de ferro normais ou até altos. Outra característica é a presença de células anormais chamadas "sideroblastos em anel" na medula óssea. Isso acontece porque há um acúmulo patológico de ferro dentro das mitocôndrias (que são como as "usinas de energia" das células), visível através de um exame especial chamado coloração de Perls. Esse grupo inclui a anemia sideroblástica adquirida (cuja causa pode ser desconhecida) e as anemias sideroblásticas constitucionais (aquelas com as quais a pessoa já nasce). Entre as anemias sideroblásticas constitucionais, existem aquelas que fazem parte de síndromes (como a Síndrome de Pearson, a miopatia mitocondrial e anemias sideroblásticas, a anemia sideroblástica ligada ao cromossomo X com ataxia, e a síndrome de anemia megaloblástica responsiva à tiamina). Há também as anemias sideroblásticas que não fazem parte de uma síndrome, incluindo tipos ligados ao cromossomo X ou de herança autossômica recessiva (termos que descrevem como a condição é herdada geneticamente).

A Case of Mitochondrial Myopathy, Lactic Acidosis and Sideroblastic Anemia (MLASA Syndrome) and Long QT Interval in a 10-Year-Old Saudi Child.

Saudi journal of medicine &amp; medical sciences2026

MLASA syndrome is a rare mitochondrial disorder that presents in three distinct genetic forms: MLASA1, MLASA2, and MLASA3; MLASA1 is the most common form. The clinical features include mitochondrial myopathy, lactic acidosis, and sideroblastic anemia. Although presence of other features is not uncommon, its association with long QT (LQT) syndrome has not been described before. In addition, while MLASA syndrome has been reported from several countries worldwide, we present the first patient with MLASA1 syndrome from the Kingdom of Saudi Arabia in this case report. The 10-year-old girl with history of poor health since infancy and recurrent hospital admissions for infections and blood transfusions was referred to our hospital for allogeneic bone marrow transplantation. Early in her childhood, she was diagnosed with symptomatic LQT syndrome and, at a later age, with sideroblastic anemia. Whole-exome sequencing (WES) revealed homozygous mutations in the PUS1 gene and heterozygous mutations in the KCNQ1 gene. The WES test of the parents was negative, and there was no family history suggestive of a similar diagnosis. Therefore, our patient has most probably developed the syndrome as a result of a sporadic de novo mutation; however, the possibility of sex cell germline mosaicism cannot be excluded. Heterozygous KCNQ1 gene mutation is associated with the development of type 1 LQT syndrome. Detection of the MLASA syndrome and proper intervention at an early age are crucial for successful management. Associated LQT syndrome should always be anticipated. Despite the presence of a fully tissue-matched sibling, the parents of our patient declined the option of allogeneic bone marrow transplantation due to potential severe cardiac and liver complications.

Sideroblastic anemia with B-cell immunodeficiency, periodic fevers, and developmental delay (SIFD), a rare multisystemic syndrome, occurs due to loss-of-function mutations in the tRNA nucleotidyl transferase 1 (TRNT1) gene. This study reports the case of a 21-month-old female patient with SIFD and compound heterozygous mutations c.824T > A, p.Leu275X (a novel variant) and c.1246 A > G, p.Lys416Glu in TRNT1 gene. The patient had presented with recurrent fever since 10 days of age, along with vasculitis, systemic inflammation with elevated proinflammatory cytokines, decreased B-cell count, and failure to thrive. Furthermore, she did not respond to intravenous immunoglobulin (IVIG) treatment, but her condition stabilized with etanercept (a tumor necrosis factor [TNF] inhibitor) and corticosteroids therapy. In addition, this study includes a systematic review of the clinical presentations, genetic mutations, treatments, and outcomes of 75 patients with SIFD. The estimated 2-, 5-, and 10-year Kaplan–Meier survival probabilities for all patients were 88.45%, 76.67%, 68.84% for all patients; 82.40%, 58.86% and 44.85% for patients with onset age of ≤ 3 months; 70%, 40% and 26.68% for patients with seizures; 88.05%, 66.62% and 59.22% for patients with decreased B cell number; 50% and 33.33% for patients who received hematopoietic stem cell transplantation (HSCT), respectively (log-rank P < 0.05). We concluded that younger age of onset of ≤ 3 months, seizures, and decreased B-cell count are significant poor prognostic factors for survival. Anti-TNF therapy early in life may stabilize patients with autoinflammatory phenotypes; however, the role of HSCT remains controversial.

A novel frameshift deletion in SLC25A38 and its role in mitochondrial dysfunction: A case study of sideroblastic anemia in a child from Iran.

Annals of hematology2026 Feb 20

Sideroblastic anemia (SA) is a rare hematological condition characterized by the accumulation of iron in the mitochondria of erythroid precursor cells, resulting in the formation of sideroblastic rings. It occurs in both inherited and acquired forms. A prevalent subtype of congenital sideroblastic anemia (CSA) results from autosomal recessive mutations in the SLC25A38 gene. This investigation included a clinical and genetic evaluation of a family with a child diagnosed with pyridoxine-refractory SA. Whole Exome Sequencing (WES) was performed on the patient to detect the genetic variation. Afterwards, to examine segregation, Sanger sequencing of the related gene was conducted on the patient’s parents and the fetus of this family. On the other hand, the proband’s aunt and her husband, whose daughter died from symptoms similar to SA, were also evaluated for this variation. The next step involved molecular docking studies for the SLC25A38 protein pre- and post-variation. The WES analysis demonstrated the c.482_485del (p. Ile161ThrfsTer4) variant in the SLC25A38 gene, present in the probands as homozygotes and in the parents as heterozygotes. The chemical binds and stability of the protein in the mutant form was observed to be diminished in comparison to the wild form. This study enabled the reclassification of the SLC25A38: c.482_485del from likely pathogenic to pathogenic, which will significantly assist specialists in making decisions about this variant.

Correlation of MLASA2 Clinical Phenotype and Survival with Mt-TyrRS Protein Damage: Linking Systematic Review, Meta-Analysis and 3D Hotspot Mapping.

Current issues in molecular biology2026 Jan 16

Myopathy, Lactic Acidosis, and Sideroblastic Anemia type 2 (MLASA2) is a rare mitochondrial disorder caused by pathogenic variants (PVs) in the YARS2 gene (which encodes the Mt-TyrRS protein. We performed a comprehensive clinical-molecular synthesis by integrating a systematic review and meta-analysis of all published MLASA2 cases with survival modeling and three-dimensional structural mapping. Across the aggregated cohort, anemia (88.6%), sideroblastic phenotype (85.7%), and lactic acidosis (82.9%) were the most prevalent phenotypes. Fifteen PVs were identified, dominated by p.(Phe52Leu) (29.4%). Survival estimates were 94.1% at 10 years, 70.7% at 30 years, and 42.4% at 50 years; cardiomyopathy and diagnosis before age 10 were associated with decreased survival. We generated the first 3D structural map of all reported Mt-TyrRS PVs, identifying nine spatial hotspots across catalytic, anticodon-binding, and tRNA-binding domains. An integrated framework combining structural density, clinical severity, in silico predictions, and ΔΔG destabilization classified three clusters as High-risk, three as Medium-risk, and three as Low-risk. Among them, cluster 3, a large catalytic hotspot encompassing 44 residues and including nearly half of all MLASA2 cases, showed the strongest pathogenic convergence. This clinical-structural integration provides new insights for a better comprehension of MLASA2, enhancing variant interpretation and improving diagnostic and prognostic precision.
