Rationale: This study presents a case of hemoglobin M disease (HMD), a rare inherited disorder characterized by persistent cyanosis and hypoxemia, observed across 3 generations within a single family. The diagnosis of HMD poses significant challenges, particularly in asymptomatic individuals, due to its rarity and the subtlety of its symptoms. Notably, there is a scarcity of reports on methemoglobinemia in pediatric populations, which further complicates early detection and intervention.

Background: Aromatic L-amino acid decarboxylase (AADC) deficiency is a rare life-threatening inborn error of neurotransmitter biosynthesis. It is characterized by deficient biosynthesis of neurotransmitters dopamine and serotonin, leading to catecholamines deficiency and sympathetic deprivation, while the parasympathetic system remains functional. Since 2012, gene therapy has led to clinical improvements in symptoms and motor function with a severe phenotype.

Background: The mitroaortic intervalvular fibrosa is an avascular structure near the left ventricular outflow tract, between the mitral and aortic valves. Mitroaortic intervalvular fibrosa complications, such as tamponade, hemopericardium, and abscesses, are rare and often diagnosed postmortem. On the other hand, the COVID-19 pandemic notably impacted pediatric patients with congenital heart diseases, who frequently presented cardiac complications including arrhythmias, elevated troponins, myocarditis, and heart failure.

The cytoskeleton, composed of microtubules, intermediate filaments and actin filaments is vital for various cellular functions, particularly within the nervous system, where microtubules play a key role in intracellular transport, cell morphology, and synaptic plasticity. Tubulin-specific chaperones, including tubulin folding cofactors (TBCA, TBCB, TBCC, TBCD, TBCE), assist in the proper formation of α/β-tubulin heterodimers, essential for microtubule stability. Pathogenic variants in these chaperone-encoding genes, especially TBCD, have been linked to Progressive Encephalopathy with Brain Atrophy and Thin Corpus Callosum (PEBAT, OMIM #604,649), a severe neurodevelopmental disorder.

Unlabelled: Spondyloenchondrodysplasia (SPENCD) is a rare genetic disorder characterized with skeletal dysplasia, immune dysregulation, and neurological impairment. Patients diagnosed with SPENCD at a single pediatric hematology center were included in the study. The patients' clinical characteristics, symptoms at presentation, imaging and laboratory results, and genetic analysis results were collected retrospectively from their files.
