%X Sotos syndrome is characterized by tall stature, advanced bone age, typical facial abnormalities, and developmental delay. The associated gene is NSD1. The study involved 22 patients who fulfilled the clinical criteria. Phenotypic characteristics, central nervous system findings, and cardiovascular and urinary tract abnormalities were evaluated. Meta-analysis on the incidence of cardinal clinical manifestations from the literature was also performed. Macrocephaly was present in all patients. Advanced bone age was noted in 14 of 22 patients (63%), and its incidence presented significant statistical difference in the meta-analysis of previous studies. Some patients had serious clinical manifestations, such as congenital heart defects, dysplastic kidneys, psychosis, and leukemia. Clinical and laboratory examinations should be performed to prevent and manage any unusual medical aspect of the syndrome. Facial gestalt and macrocephaly, rather than advanced bone age, are the strongest indications for clinical diagnosis.
