New Research Reveals Key Clue in Huntington Disease Progression
A recent study conducted by scientists at UBC’s Centre for Molecular Medicine and Therapeutics and BC Children’s Hospital Research Institute has shed light on why some individuals with Huntington disease experience symptoms much earlier than others.
Published in the scientific journal Neuron, the study pinpointed a specific genetic variant that appears to accelerate the disease by triggering excessive DNA changes in the brain’s most vulnerable neurons. Dr. Michael Hayden, the senior study author, emphasized that this discovery could be a crucial step towards understanding and potentially treating Huntington disease more effectively.
Huntington disease is an inherited disorder characterized by involuntary movements and psychiatric issues, with the genetic mutation present in all cells of the body but primarily affecting nerve cells in the brain. Individuals carrying the identified genetic variant showed significantly larger expansions of the Huntington mutation in their neurons compared to those without the variant, occurring at a much higher frequency.
The findings suggest that targeting the expansion of the DNA mutation could be a promising therapeutic approach to delay the progression or onset of Huntington disease. This breakthrough provides scientists with valuable insights into the mechanisms underlying the disease and offers hope for improved treatment strategies in the future.
