Most of these babies do not survive once they enter the adolescent age. The maximum period of survival age is not above 30 years, in which case heart stoke is the major cause of death.

It has been also been discovered that about 90% of the progeria afflicted children have a gene which encodes Lamin A protein (LNMA), which is a fibrous protein that happens to be involved in the nuclear membrane structure.
