Area of Science:

  • Genetics
  • Biochemistry
  • Neurology

Background:

  • Wilson disease is an inherited disorder affecting copper transport.
  • Clinical manifestations are diverse, including neurological, hepatic, and psychiatric symptoms.
  • Onset age ranges from 3 to 50 years, complicating diagnosis.

Purpose of the Study:

  • To summarize the challenges in diagnosing Wilson disease.
  • To highlight the genetic basis and mutational landscape.
  • To emphasize the importance of early molecular diagnosis and treatment.

Main Methods:

  • Review of clinical and biochemical features.
  • Genetic analysis of copper-transporting ATPase gene mutations.
  • Discussion of diagnostic strategies and treatment options.

Main Results:

  • Over 80 mutations identified in the copper-transporting ATPase gene.
  • Mutation frequencies vary significantly across ethnic groups.
  • Specific common mutations in European and Asian populations can aid diagnosis.
  • Molecular analysis offers definitive diagnosis for asymptomatic relatives.

Conclusions:

  • Wilson disease diagnosis is challenging due to variable presentation.
  • Genetic analysis is vital for accurate diagnosis, especially in families.
  • Timely treatment with chelating agents or zinc is essential to prevent irreversible damage.
