I think genetics are completely misunderstood. I also have serious Narcissism in my family and to me it very much looks like that's the world view you learn if that's how it's demonstrated to you as a small child. Small children have no filter on inputs also. If dad isn't around because mother is unbearable and she lives a narcissistic reality it becomes the water that you swim in. I don't think there is genetic code that determines that you think other people are to blame for everything!

Random theory: Children of narcissists like IT because it's a world that is very predictable with rational explanations.
