The Dutch woman who was the oldest person in the world when she died at the age of 115, appears have rare mutations in her DNA. Henny van Andel-Schipper was born in 1890 and became the word's oldest person in May 2004 before her death in August the following year. What made her even more remarkable was the fact she remained mentally sharp right up until her death.
She showed no signs of Alzheimer's disease which most experts assume would be inevitable for someone of her years. Nor did she suffer from any other conditions normally associated with people who live over the age of 100 such as hardening of the arteries. Now, six years after her death she has become the oldest person to have her complete genetic code sequenced as scientists hope to unlock the secrets to her good health and longevity.The Presurfer
