Men with a 47,XYY karyotype do not present with a well-defined clinical syndrome. The diagnosis relies entirely on the cytogenetic demonstration of two Y chromosomes, accompanying an otherwise normal set of chromosomes. Cases with 47,XYY/46,XY mosaicism are also subsumed under the XYY male category. The 48,XXYY karyotype is briefly discussed in Chapter 9.4.3.
