Question
discussion involves two videos. The first video shows the effects of Hutchinson-Gilford Progeria Syndrome on aging. Progeria is a genetic disorder that results in accelerated aging. The disorder is caused by a spontaneous mutation in the gene LMNA (prounounced “lamin-a”). The second video is about Brooke Greenberg. Brooke was a 20-year-old women with Syndrome X who had not aged since 5 years old. Brooke lost her battle with Syndrome X last year. Research shows that there are only 2 others like Brooke. Their study continues to find the key to aging.

Video 2: Brooke Greenberg story -- https://www.youtube.com/watch?v=kwTsRzbgBOU
Watch both videos, then compare and contrast the videos focusing on the role each genetic disorder plays on the aging process.
Explanation / Answer
1. Progeria is an extremely rare genetic disorder where aging occurs at a very early age (8 to 10 times faster than the normal children). The word itself means 'premature old age', and only 100 children in the world has been diagnosed with it. The average life expectancy with this disease is 13 years. Progeria is caused by a mutation in the gene lmna. In this video, a girl named Lindsey is diagnosed with the same, although her mind is still young her body is aging much faster and explains how difficult her life is.
2. Brooke Greenberg was diagnosed with syndrome X (the doctors couldn't actually identify the cause so the named it X), where unlike progeria she doesn't age. She was born with anterior jip dislocation which was surgically corrected. Between the age four and five, her growth suddenly stopped. No genetic condition was found which could be linked to the disease like progeria, but various parts of her body were diagnosed to be aging at a different rate.
