Hello,
Thank you for reaching out to Dr. Galen. Please find the below response to your query.
Yes, genetic testing can be used to identify the presence of the gene mutation responsible for Huntington disease. Specifically, DNA testing is conducted to detect the presence of CAG repeats, which are characteristic of the disease. This testing allows individuals to determine if they carry the mutation and assess their risk of developing Huntington disease.
