NIH researchers link chromosome region to gigantism
Researchers at the National Institutes of Health have found a duplication of a short stretch of the X chromosome in some people with a rare disorder that causes excessive childhood growth. They believe that a single gene within the region likely has a large influence on how much children grow. The research comes from a lab at NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), which seeks to understand growth.
“Finding the gene responsible for childhood overgrowth would be very helpful, but the much wider question is what regulates growth,” said Constantine Stratakis, M.D., D.Sc., lead author of the new paper and the scientific director of theDivision of Intramural Research at NICHD.
