A child with mitochondrial DNA deletion experienced pancreatic exocrine insufficiency. Despite developing other Pearson syndrome features, bone marrow was unaffected, highlighting the variability of mitochondrial disorders.

Area of Science:

  • Genetics
  • Pediatrics
  • Neurology

Background:

  • Mitochondrial DNA deletions are rare genetic disorders.
  • Pearson syndrome is a mitochondrial disorder characterized by specific clinical features.

Observation:

  • A pediatric case presented with pancreatic exocrine insufficiency as an initial symptom.
  • The patient later developed other characteristic features of Pearson syndrome.

Findings:

  • The patient exhibited significant pancreatic exocrine insufficiency.
  • Bone marrow involvement, typically seen in Pearson syndrome, was notably absent in this case.

Implications:

  • This case underscores the high clinical variability of mitochondrial DNA deletion syndromes.

  • The absence of a single hallmark feature should not preclude diagnostic consideration of these conditions.
