Area of Science:

  • Neuroscience
  • Genetics
  • Pharmacogenomics

Background:

  • The genetic basis of simple Mendelian inherited neurological diseases is well understood, with frequent reports of new linkage data and gene mutations.
  • However, identifying genetic variants for common complex diseases and predicting treatment responses (pharmacogenomics) presents significant challenges due to the rarity of individual conditions.

Purpose of the Study:

  • To review and discuss approaches for identifying common genetic variations associated with complex neurological diseases.
  • To address the challenges in detecting moderate genetic effects in populations, contrasting with established Mendelian genetics strategies.

Main Methods:

  • The review discusses strategies for resolving common genetic variation.
  • Likely approaches involve a combination of linkage analysis and linkage disequilibrium mapping.

Main Results:

  • Established methods effectively address Mendelian neurological diseases.
  • Developing strategies for common diseases and pharmacogenomics is an ongoing and complex area of research.

Conclusions:

  • Resolving common genetic variation underlying complex diseases requires advanced methodologies.
  • A combination of linkage analysis and linkage disequilibrium mapping is anticipated to be crucial for future discoveries in this field.
