Women get more work out of hundreds of genes on the X chromosome than men do, and that could help explain biological differences between the sexes, a study says. The results imply that women make higher doses of certain proteins than men do, which could play out in sex differences in both normal life and disease, researchers said. So far, however, none of the genes identified in the study has been linked to any such observable differences, said senior study author Huntington Willard of Duke University. He and Laura Carrel of Pennsylvania State University describe their analysis of the X chromosome genes in today's issue of the journal Nature. A second paper in the same issue presents a comprehensive analysis of the chromosome's DNA, in which an international team of scientists found 1,098 genes.
