At this point, we’re not sure if Bell’s Palsy is congenital, genetically related, or runs in the family. However, there does seem to be a predisposition within families, so if you do have somebody within your family who was had it at some point in your life, you are slightly more predisposed to getting Bell’s Palsy than the rest of the population. We don’t know why. We don’t know what genetics are involved when it’s Bell’s Palsy. If it’s facial paralysis due to other genetic disorders, it’s not called Bell’s Palsy, and then we do know.
