The signs shown in the picture above represents Klinefelter syndrome.
- The presence of an extra X chromosome in males most often occurs when the genetic material in the egg splits unevenly.
- But it can also occur when the genetic material in the sperm splits unevenly.
- Even though Klinefelter syndrome is a genetic disorder, it is not passed down through families.
- So, parents who have a child with Klinefelter syndrome are not any more likely than other couples to have another child with the condition.
