MDS 2023 | Exploring genetic testing in Parkinson’s disease

Jonathan Carr, MD, ChB, PhD, Stellenbosch University, Cape Town, South Africa, delves into the intricate relationship between genetics and Parkinson’s disease. The notion that most sporadic Parkinson’s disease cases are solely genetic is questioned, emphasizing the need for a more nuanced understanding of the disease’s etiology. Prof. Carr highlights the split nature of Parkinson’s, differentiating between young-onset and sporadic occurrences. Concerns arise about the ramifications of genetic testing and precision medicine within this context, spotlighting the current knowledge gaps and the absence of treatments focused on genetic abnormalities. Advocacy for clear guidelines and the involvement of genetic counselors becomes evident to navigate the challenges of genetic testing related to Parkinson’s disease. This interview took place at the 2023 International Congress of Parkinson’s Disease and Movement Disorders in Copenhagen, Denmark.
