Bro, i've always had the same concern. I've been hesitating for years. I would never forgive myself if my potential kid has it. But nobody really knows the odds. Me and a cousin of mine have it, but none of our parents/grandparents/uncles/aunts/other cousins have it. The cousin with a stutter has a child who doesn't stutter. I don't know man... Seems like a lottety.
