WebFeb 6, 2024 · This gene is responsible for telling your brain to create huntingtin, an essential protein. Huntingtin's exact purpose is not fully understood, but it's found in the brain as well as body tissue. What we do know about huntingtin is that it probably plays a key role in nerve cell health. It keeps them strong and prevents them from self-destructing. WebJan 1, 2011 · National Center for Biotechnology Information WebThe huntingtin gene (HTT or HD gene) tells your body how to build the huntingtin protein. You get one HTT gene from each parent. If you have Huntington’s disease, one of your parents passed on an HTT gene with a mutation (like a misprint in a book).
