Veterans help provide greater insight into Klinefelter and Jacobs syndromes

Researchers found that nearly 600,000 veterans with extra X or Y chromosomes had similar rates of occurrence to the general population, but white and Asian veterans were disproportionately affected. The study suggests that early identification of these conditions can prevent illnesses associated with Klinefelter and Jacobs syndromes.
