XYY Syndrome: Causes, Symptoms, Diagnosis, Treatment, and Management

XYY syndrome is a genetic condition that occurs when an individual has a different combination of sex chromosomes than the usual. It is a congenital condition and typically does not cause noticeable differences in the individual’s physical appearance. However, in some cases, individuals with XYY syndrome tend to be taller. This condition is commonly found in male children. The psychosocial development of individuals with XYY syndrome is generally normal. However, they may experience difficulties such as behavioral problems or learning disabilities in some cases. XYY syndrome usually occurs as a result of a random genetic change. There is no specific treatment for this syndrome, but education and support can be provided to address the difficulties that the individual may experience.

XYY Syndrome Causes

XYY syndrome occurs as a result of a genetic change in the individual’s sex chromosomes:

Random Genetic Mutations: XYY syndrome occurs as a result of a random genetic mutation during the normal division of X and Y chromosomes inherited from the parents.

Family History: XYY syndrome is generally not associated with family history.

Advanced Maternal and Paternal Age: Some studies suggest that the risk of XYY syndrome may increase in children of older parents.

XYY Syndrome Symptoms

Symptoms of XYY syndrome can vary from individual to individual:

  • Increased height
