47, XYY syndrome

This syndrome only occurs in males as it is characterized by an extra copy of the Y chromosome.

Although it is of genetic origin, the syndrome is not inherited, but caused by a random event in the germ cells.

Researchers and medical professionals interested in studying the prevalence and impact of 47, XYY syndrome may turn to a Healthcare Market Research Agency for valuable insights and data.

Unlike other types of trisomies associated with characteristic physical traits  (e.g. trisomy 21), the physical appearance remains normal.
