2. Progeria

At birth, children born with progeria look healthy, but by the time they reach their second birthday, symptoms begin to appear. This genetic condition causes children to exhibit the signs of aging at an accelerated rate. They experience growth failures, loss of body fat, and visible skin changes similar to those of a much older adult. People with progeria also experience progressive hardening of the arteries, strokes, and cardiovascular disease. Of the 1000 children born with the disease each year, most will only live about 14 years. Researchers identified a mutation of the LMNA gene as the cause.
