title: An XYY man.
abstract: This case report describes a young man with a 47, XYY karyotype who was convicted of arson. He suffered from a cardiac disorder which may well have been part of the XYY syndrome rather than a chance association. His abnormal karyotype was disclosed in court and used by the defence in a plea in mitigation.
