Le persone con la Sindrome 48,XXYY possono lavorare? In quale tipo di lavori?

There is no reason why KS people can't work in any field. As KS affects different people in different ways then the ranges of intelligence can vary greatly.

Take myself for instance - I was involved in I.T. for over 25 years at some of the highest levels of the industry and then changed my career quite dramatically by running my own company selling the worlds only hypo-allergenic fitness supplement - completely designed by myself.

Obviously there are issues with KS that can cause problems with authority and some jobs may be unsuitable or more specifically a much greater challenge as most KS people suffer with social anxiety.
