Overview

48,XXYY syndrome is a sex chromosome anomaly.

It was previously considered to be a variation of Klinefelter's syndrome. It is still considered a part of the syndrome by some definitions.^[1]

Incidence

It affects one in every 18,000-40,000 male births. ^[2]

Presentation

Common features include tall stature, gynecomastia, truncal obesity, skin ulcers, and a craniofacial dysmorphism described as a "pugilistic" facial appearance.

History

The first published report of a boy with a 48,XXYY karyotype was by Sylfest Muldal and Charles H. Ockey in Manchester, England in 1960.^[3] It was found in a 15-year-old mentally challenged boy who had signs of Klinefelter syndrome; eventually, it appeared that he didn't have the Klinefelter Syndrome but, as shown above, the XXYY syndrome.
