Unraveling the genetics of social behavior and cognitive abilities, researchers at the University of Utah and the Salk Institute for Biological Studies have traced the role of two genes,GTF2I and GTF2IRD, in a rare genetic disorder known as Williams Syndrome.

Their results, published in the Feb. 9, 2009, online edition of the American Journal of Medical Genetics, suggest that GTF2IRD1 contributes to visual-spatial performance while GTF2I plays a role in social behavior. These findings illuminate the most complex aspects of being human. (Read entire article)

While it may come as no surprise that genes may help explain why some people have many friends and others have few, the researchers said, their findings go just a little farther than that.

"Some of the things we find are frankly bizarre," said Nicholas Christakis of Harvard University in Massachusetts, who helped conduct the study.(Read entire article)
