AbstractIntroduction: Tall stature is defined as length or height more than two standard deviations above the mean for age of the reference population. There are different causes of tall stature from a familial trait or a transient anticipation of growth with no major consequences to growth disorders, such as endocrine disorder and syndromic conditions like overgrowth syndromes. Case Presentation: In this study, we reported the case of a 7-year-old girl with tall stature from birth. The patient showed a generalized overgrowth, associated with extremely advanced bone age, dysmorphic features such as a broad forehead and large extremities, and a slight neurodevelopmental delay. Laboratory tests were normal, and the main hormonal disorders were ruled out. The diagnosis of overgrowth syndrome was suspected according to the clinical presentation, and the diagnosis of Weaver syndrome was confirmed by the finding of the pathogenic mutation c.2050C > T p.(Arg684Cys) in EZH2 gene through next generation sequencing (NGS). Conclusions: Our patient showed phenotypical features related to different overgrowth syndrome characteristics. We underlined the difficulties in reaching a clinical diagnosis in presence of tall stature. The role of molecular biology, particularly genetic analysis by NGS approach, should be considered in cases of tall stature with phenotypic overlap.en
