Background: The detection of sideroblastic anemia in a newborn may suggest developing Pearson syndrome. The prognosis of these patients is severe and death occurs in the first 3 years of life, so it is important to find new ways of diagnosis. Case Presentation: In the case of our patient the diagnosis was supported only at the age of 5 months, highlighting the difficulties of diagnosis at this age.

Conclusions: The diagnosis of Pearson syndrome with neonatal onset is difficult to sustain or even impossible at that age. This diagnosis can be confirmed and supported during disease progression.

Article Synopsis
  • Primary adrenal insufficiency (PAI) is a rare condition in children marked by low production of important hormones, leading to nonspecific symptoms that can make early diagnosis challenging but crucial for effective management.
  • A study was conducted with 29 patients diagnosed with PAI at an average age of 5.6 years, revealing various underlying causes, including genetic conditions and autoimmune issues, with many patients experiencing an adrenal crisis at onset.
  • Common signs of PAI include asthenia, hyperpigmentation, and hyponatraemia, but even in their absence, the possibility of PAI should still be considered, particularly as ACTH levels remain high despite treatment.

Long-term hematopoietic dysfunction in patients with large-scale mitochondrial DNA deletion syndromes.

Article Synopsis
  • Pearson syndrome (PS) and Kearns-Sayre syndrome (KSS) are mitochondrial DNA deletion syndromes with PS causing severe childhood cytopenia and KSS having later onset without blood-related issues, both sharing a common mitochondrial DNA deletion.
  • A study of 16 patients revealed that 75% had cytopenia, with many needing blood transfusions, and even after achieving transfusion independence, they showed persistent bone marrow (BM) dysfunction.
  • The research highlights that BM dysfunction is a consistent finding in SLSMD syndromes, which raises concerns about potential clonal evolution and chromosome 7 abnormalities, underscoring the need for specialized hematological monitoring for these patients.

Significance of Variants of Uncertain Significance: The Human Cost of Genetic Uncertainty.

Am J Med Genet C Semin Med Genet

November 2024

Department of Pediatrics, Division of Clinical Genetics and Genomics, Weill Cornell Medicine, New York, New York, USA.

This piece narrates the journey of Maria (name of the mother has been altered to protect the family's privacy), a new mother confronting her newborn's unexpected diagnosis of very long chain acyl-CoA dehydrogenase (VLCAD) deficiency, despite undergoing proactive genetic carrier screening within a consanguineous marriage. It highlights the emotional and systemic challenges arising from the lack of diversity in genetic databases, which, in this case, failed to detect pathogenic variants in Maria and her husband. Maria's story sheds light on situations where a masked variant of uncertain significance (VUS) necessitates consultation with a trained genetics specialist and underscores the urgent need for a more equitable healthcare system.

Very long-chain acyl-CoA dehydrogenase (VLCAD) deficiency is a rare genetic condition affecting the mitochondrial beta-oxidation of long-chain fatty acids. This study reports on the clinical outcomes of patients diagnosed by newborn screening with VLCAD deficiency comparing metabolic parameters, enzyme activities, molecular results, and clinical management. It is a single-center retrospective chart review of VLCAD deficiency patients who met the inclusion criteria between January 2002 and February 2020.
