[Menke's disease. A case report (author's transl)]

Insights

Menkes disease, a rare genetic disorder, presents with low copper and torturous intracranial arteries in a 7-month-old male. While extracranial arteries appear normal, the condition may contribute to central nervous system hypomyelination.

Area of Science:

  • Neuroscience
  • Genetics
  • Biochemistry

Background:

  • Menkes disease is a rare X-linked recessive disorder caused by mutations in the ATP7A gene, leading to impaired copper transport.
  • Copper is essential for various enzymes involved in brain development, including those crucial for myelination.
  • Hypomyelination, a hallmark of Menkes disease, results in neurological deficits due to insufficient myelin sheath formation.

Observation:

  • A 7-month-old male diagnosed with Menkes disease exhibited characteristic symptoms.
  • Biochemical analysis revealed significantly low serum copper and ceruloplasmin levels.
  • Cerebral angiography demonstrated tortuosity in all intracranial arteries.

Findings:

  • Despite the intracranial vascular abnormalities, a biopsy of an extracranial artery (temporal artery branch) showed normal histology.
  • The study highlights the specific pattern of vascular involvement in Menkes disease, predominantly affecting intracranial vessels.
  • The findings correlate with known copper deficiency-induced effects on connective tissue and vascular integrity.

Implications:

  • This case underscores the importance of early diagnosis and management of Menkes disease to mitigate neurological damage.
  • Understanding the vascular manifestations, particularly intracranial tortuosity, may aid in diagnosing and predicting disease progression.
  • Further research into the mechanisms linking copper deficiency to hypomyelination and vascular abnormalities is warranted.
