Did you know

Klinefelter syndrome is a chromosomal condition in boys and men that can affect physical and intellectual development. Its signs and symptoms vary among affected individuals. In some cases, the features of the condition are so mild that the condition is not diagnosed until puberty or adulthood, and researchers believe that some affected men and boys are never diagnosed. Klinefelter syndrome affects 1 in 500 to 1,000 newborn boys. It is among the most common sex chromosome disorders.
