Scientists are studying the girl, not growing for 16 years

U.S. scientists hope to solve the riddle of aging, genome 17-year-old girl, who hitherto physically and mentally remains at one year old chield. For example, it will be able to identify such genes, to penetrate into the mechanisms of their work and learn how to manage them, hopes to Richard Walker of the Medical School, University of South Florida, leading the research.

Brooke Greenberg weighs 16 pounds (just over 7 kg), and its growth is only 30 inches (75 cm). Preliminary studies of DNA suggest that the girl does not grow because of failures in the genes corresponding to those of normal people for aging, quotes a British newspaper InoPressa.

Brooke, who lives with his parents and sisters in the suburbs of Baltimore, in fact, stuck in time ", says the publication. She has a noticeable development: she learned to crawl, smile and laugh. But she does not grow, can not speak, she never replaced baby teeth.

At the same time, the girl has serious health problems, rather typical for the elderly. Studies indicate that some organs Brook age, but slower and not as ordinary people.

Father Brook Ginberg said that he agreed to further research to help other people. Experts do not exclude that in the end because of their investigations will be able to answer the question of why men are mortal.

"Scientists have recently made several revolutionary discoveries, proving that with a shallow" editing "of individual genes can be extremely extended lifespan of many animals - worms and mice, the magazine writes. "In terms of genetic mouse - very close relatives of people", - underlined Cynthia Kenyon, a biochemist at the University of California at San Francisco.

The assumption that the aging control several key genes, shared Elina Slagboom, University of Leiden in Holland, a professor of molecular epidemiology. It collected data on 30500 individuals of the clan long-lived and concluded that they simply slower aging.

According to British scientists at the University of Leicester, the genes inherited from both parents, can make a person to age in a number of biological traits to be 8 years older than those who have this genetic material is missing. This combination of genes is approximately 7% of the population.

Another 38% of people because of the genes in the average "old" peers for 4 years. In 55% of the population that genetic material does not occur.
