The symptoms of disease you have listed here are derived from every possible karyotype that has been associated with Klinefelter's syndrome, but since the vast majority of males with KS are likely to have the 47XXY karyotype, which occurs between 1:500 to 1:1000 live male births, then those symptoms of disease ought to be given greater emphasis as they're the ones most likely to be seen.
The vast majority of XXY males are not diagnosed at all, whereas those with more the 1 additional X are very likely to be diagnosed, in comparison to XXY's as they have much more obvious symptoms, such as mental subnormality, or much more severe learning difficulties.
I recommend this page for New Zealanders to visit as even though the booklet presented was originally written by the American's (thank you very much) this version has specific to New Zealand education information. The site has also been designed for smartphone access.
