Patient description (medical language): A 9-year-old girl is brought to the office for evaluation of short stature and overweight body habitus. The patient's mother and father are 170 cm and 181 cm tall, respectively.  On physical examination, the patient's height is in the 5th percentile of her age.  Other findings include low-set ears, a high arched palate, a webbed neck, and cubitus valgus.  Chromosomal analysis reveals a 45, XO karyotype.

Patient description (patient's own words): I took my 9-year-old daughter to the doctor because my mother-in-law kept saying she seemed small and overweight. My husband and I are 170 cm and 181 cm tall, respectively. The physical health highlighted that she is in the 5th percentile of her age. The doctor said that she has low-set ears, a high-arched palate, a webbed neck, and cubitus valgus. She also did a chromosomal analysis, which revealed a 45, XO karyotype.
