Dunno, son is normal and so are both parents.
My Pop was safety officer for the police shooting team and he tried to teach me gave up and stated I would never shoot. He refused to allow me to shoot left handed. Snuck off n bought a BB gun (was not allowed a BB gun per my mischievous disposition), next time out whipped him and all my uncles n cousins as I just shot left handed before he could "correct" me!! LOL he had never heard of this.
