Gene variants, including mutations, can be either inherited or acquired. An inherited gene mutation, as the name implies, is inherited from a parent, so it’s present in the very first cell (once the egg cell is fertilized by a sperm cell) that eventually becomes a person. Since all the cells in the body came from this first cell, this ...
