Amber Southwell

Dr. Amber Southwell’s research focuses on the development of therapeutics for Huntington’s disease (HD). HD is an inherited, fatal neurodegenerative disorder characterized by involuntary movement, psychiatric disturbance, and cognitive decline. Despite the simple genetic nature of HD and the concurrent ability to identify mutation carriers decades before disease onset, there is currently no therapy available that can delay onset or slow progression. Southwell is using antisense oligonucleotides targeted to single nucleotide polymorphisms associated with the HD mutation as a strategy for selectively silencing expression of the HD causative mutant gene.
