OBJECTIVES: ) gene at Xq27.3-q28 underlie a rare but clinically distinctive genetic syndrome. This report aims to describe the clinical features of a pediatric male patient presenting with morbid obesity, hypogonadism, gynecomastia, short stature, and neurodevelopmental disorders, and to compare the findings with previously reported cases.
