ClinGen Actionability GCH1

From SNPedia

This is a genotype with recommended actions if clinically confirmed. In brief:

  • Be aware that penetrance varies widely, including between genders.
  • Have an exam by a movement disorder specialist at least several times a year.
  • If diagnosed, consider levodopa administration.
  • Evaluate relatives at risk in order to identify as early as possible those who would benefit from initiation of treatment.
