Aging is a complex process, which exists because evolutionary pressure decreases once an organism has lived past its reproductive lifespan. There is not one source of damage that leads to aging, or a small number of genes that lead to aging. Many things start going wrong in the body because there is no evolutionary, selective pressure for the problems to be fixed. There is not a single gene that if mutated will lead to immortality. This girl will eventually die; her body will not last much beyond the average lifespan of a normal human. This is because all the other genes in her body have never been selected for to work past the range of a normal human lifespan.
