Abstract

Tall stature is a common feature of both Marfan syndrome and XYY syndrome. Differential diagnosis between these entities has important prognostic implications. We report the case of a 21-year-old young man with a previously known diagnosis of XYY syndrome, in whom the identification of a fibrilin-1 mutation was determinant to establish an appropriate diagnosis, medical follow-up, and genetic counselling.
