You and your child will be eligible to participate if:
- He is between the ages of 8 and 18 years
- Is able to read at the First Grade Level
- If you are willing to have your child receive a genetic test if he has not had one to determine if he has KS.
We are seeking boys with and without KS.
Special Note:
In the event an affected (47 XXY) boy is unaware of his diagnosis, non-disclosure will be maintained as per the parent wishes.
Since we are measuring affected and non-affected boys, participants may not be aware if they are affected or not.
