However it is possible to have identical twins that are both affected with the disease. But because each case is a new sporadic mutation, it is also possible to have one twin with progeria and one without the disease. There are three main theories as to why progeria occurs. Until more research can be done on the genetic basis of progeria and Werner s syndrome, the cause will remain a mystery. Without futher evidence to support any of the proposed theories, efficient treatment and prevention can not be administered.
More research is in progress, but our lack of understanding about the disease slows the process.
With advances in technology comes more opportunity to finally locate and understand the affected gene or genes that cause progeria and steps toward finding a treatment, cure, and preventative measures can be taken.
