Is there any specific group that is affected more by Klinefelter's Syndrome?
Racially speaking, no, all racial and ethnic groups are about equal in how much they are afflicted by the disorder, no matter which group a person might belong to. However, of these groups, only in men can it be found. Klinefelter's Syndrome cannot be in women. If you are a female, congratulations! You cannot have this disorder.
Who else is affected?
Obviously, family and friends will need to put up with this disorder. Although someone with Klinefelter's Syndrome will lead a typically normal life, other people such as their peers will need to understand the symptoms of this abnormality before they can pass judgement on any afflicted people.
