Extra Chromosome X

[Chromosome-X]

Yesterday the doctor found out my son has an extra X chromosome do you have any information about this?

[Kevin Kennedy, Ph.D.]

The presence of an extra X chromosome results in a condition called Klinefelter's Syndrome (named after the physician who detected it). I won't go into details about it here, because there is plenty of information available. Simply do an internet search for Klinefelter's Syndrome, and you'll find useful details.
