Huge Genetic Variation Found in Human Beings
Posted: Thursday, July 12, 2001
WASHINGTON (Reuters) - The notion of a uniform genetic blueprint for human beings took a tumble on Thursday, as the most detailed examination yet of variations in the genetic makeup of people detected unexpectedly large individual differences.
Researchers with Genaissance Pharmaceuticals Inc. of New Haven, Connecticut, found astonishing variance at the genetic level in 82 unrelated people primarily from four racial backgrounds -- white, black, Asian and Hispanic.
In studying 313 genes -- out of the 30,000 identified by human genome scientists -- the Genaissance researchers found that for each gene, there actually are on average 14 versions that can be inherited by a given person from parents.
The researchers said their findings should cause scientists to rethink the definition of the human genome, or genetic map. [More]
