Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) is a mitochondrial disorder. A 9-year-old boy with asthma and depression was diagnosed with MELAS due to abnormal mitochondria and a specific genetic mutation.

Area of Science:

  • Genetics
  • Neurology
  • Mitochondrial Biology

Background:

  • Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) is a significant multisystemic mitochondrial disorder.
  • The typical MELAS phenotype is often associated with a specific point mutation (A to G transition at nucleotide 3243) in mitochondrial DNA.

Observation:

  • A 9-year-old male patient presented with chronic asthma and depression.
  • Diagnostic evaluation revealed abnormal mitochondria and partial defects in respiratory chain enzymes.

Findings:

  • The patient was found to have the characteristic MELAS point mutation in his mitochondrial DNA.
  • This case links the MELAS mutation to a presentation involving chronic asthma and depression.

Implications:

Related Experiment Videos

  • Highlights the diverse clinical manifestations of MELAS beyond classic neurological symptoms.
  • Suggests the importance of considering mitochondrial disorders in pediatric patients with complex, seemingly unrelated symptoms.
  • Underscores the role of genetic testing in diagnosing mitochondrial disorders.
