A 54 year old male came for his yearly physical and has complained of recently having a difficult time reaching for the telephone when it rings and even picking up the telephone once he is able to reach it. He has no prior history of this sort of weakness so you ask him if anyone in his family also experienced this sort of trouble as they began to age. He explains to you that his father did start to have a hard time performing tasks and movements with his extremities and eventually had a very difficult time speaking, breathing, and eating. You think you have an idea of what disease this man could have been inherited and genetic testing is done showing an autosomal dominant genetic mutation. What is the most likely result?
