There's this other famous one where this gene low-density lipoprotein receptor-related protein 5, or LRP5 causes extra bone density. usually when LRP5 is inhibited or impaired, this causes osteoporosis, but when it is mutated a different way, it can cause increased bone density. a bunch of generations of a family had never broken a bone in their life because of this. cool stuff.
