Klinefelter Syndrome? Worried my younger brother might have it?

Worried my brother may have klinefelter syndrome? Questions?I am really worried, we are going to the doctor tomorrow. I have some questions about it.

1.) He is only 9years old. Is that too young to tell?
2.) He has some "man boobs", but he is not over weight, if anything he is underweight. is that a symtom?
3.) He also stutters a lot when speaking is that also a symtom?

Thanks for your help.

Answers would be greatly appreciated?

Klinefelter's Syndrome is a genetic disorder, so he could be tested at any time for a diagnosis. Nine is not too young, most boys are not diagnosed until older because infertility is the most common trait.
Stuttering is not a symptom per se, and neither is extra fat in the chest.
It is not treatable, because it is a genetic disorder, but there really are very few things that would cause a life altering issues. Some boys with klinefelter's have trouble learning, but it's quite mild compared to other disorders, and is based on the number of X chromosomes in his genes.

Good luck and how wonderful that you are being so supportive of your family and caring about your little bro!
