It has been awhile since a review of CAG counts in Huntington's Disease was published, so the new article by Dr. Michael Hayden and colleagues is very helpful. The normal, intermediate, and reduced penetrance ranges have changed over time and there have also been errors in publications. The authors present the most current information in the table below.
