This review covers mitochondrial cytopathies in children and adolescents, focusing on genetic causes and clinical features. It details respiratory chain complex deficiencies stemming from mitochondrial or nuclear DNA defects.

Area of Science:

  • Genetics
  • Biochemistry
  • Pediatrics

Context:

  • Mitochondrial cytopathies are a group of inherited metabolic disorders.
  • These conditions often manifest in childhood or adolescence.
  • Deficiencies in mitochondrial respiratory chain complexes are a primary cause.

Purpose:

  • To review the genetic, biochemical, clinical, diagnostic, and therapeutic aspects of mitochondrial cytopathies.
  • To differentiate between mitochondrial DNA (mtDNA) and nuclear DNA (nDNA) alterations.
  • To highlight the significance of these disorders in pediatric and adolescent populations.

Summary:

  • This review examines mitochondrial cytopathies resulting from respiratory chain complex deficiencies.
  • It categorizes cases based on genetic origin: mitochondrial DNA (mtDNA) or nuclear DNA (nDNA) defects.
