This WG is multidisciplinary (neurologists, clinical geneticists, genetic counsellors, molecular geneticists, psychologists) and involves key representatives from the European Huntington Association
Our main goal is to facilitate best practice of genetic counselling for families affected by Huntington’s Disease.
This may include review and update of guidelines and recommendations in relation to genetic counselling and testing for Huntington’s Disease based on discussion of challenging ethical and legal cases and on scientific literature review.
The working group would like to provide support and training for EHDN members in relation to genetic counselling issues.

The topics for sub-group projects link to recommendations for practice.
This includes:

  • Reproductive decision-making
  • Pre-symptomatic testing
  • Diagnostic testing
  • Talking to children about HD
  • Models of support post predictive testing
  • CAG-repeat size and transmission to the next generation
  • Cultural diversity in genetic counselling practice


Previous Projects

  • Predictive Test Recommendations Review
  • Successful seed fund application for Genetic Counselling Narrative Study
  • Successful seed fund application for WG project on Intermediate Alleles
  • Contribution to the Young Adult Working Group Predictive Testing Checklist

Ongoing projects
