XYY Syndrome

47XYY syndrome is associated to higher risk for seizures focal epilepsy and an electroclinical pattern characterized by focal spike and waves (similar to benign focal epilepsy) has been described in 47XYY boys (Torniero 2010) Neuroimaging Males with 47XYY show increased total gray matter (GM) and white matter (WM) volume

Does 47 XYY affect GM volume?
Voxel-based morphology (VBM) revealed that boys with 47,XYY have altered GM volume in the insular and parietal regions relative to neurotypically developing boys (Lepage et al., 2014). Alterations in gray matter volume may account for the reduced motor coordination typically seen in 47,XYY boys.
Is 47 XYY syndrome inherited?
It is unclear why an extra copy of the Y chromosome is associated with tall stature, learning problems, and other features in some boys and men. Some people with 47,XYY syndrome have an extra Y chromosome in only some of their cells. This phenomenon is called 46,XY/47,XYY mosaicism. 47,XYY syndrome is not inherited.
What is a 47 XYY mosaic form?
In some cases, it arises during early embryogenesis in a post-zygotic mitotic error, in which case it can result in a 46,XY/47,XYY mosaic form (Robinson & Jacobs, 1999). The prevalence of 47,XYY is currently estimated at approximately 1:1000 males.
How is 47 XYY treated?
Once 47,XYY has been diagnosed, a comprehensive neurodevelopmental evaluation is important for the management of this syndrome. Occupational and physical therapy may be recommended for infants and young boys who have low muscle tone (hypotonia), and speech therapy may be needed for boys who have speech delay.
