Testing the tests.

Clinical Presentation: A 5-year-old girl of Ashkenazi origin was referred to our pediatric endocrine clinic because of short stature. The child generally had good health aside from several episodes of otitis media. She was born at term after a normal pregnancy and delivery; birth weight was 2400 g, and birth length was not recorded. There was no history of intrauterine infection, toxemia, or exposure to alcohol or drugs. Developmental milestones were achieved at appropriate chronologic ages. The father’s height was 165 cm (third percentile); his first shave was at age 151⁄2 years. Maternal height was 157 cm (25th percentile); menarche was at age 12 years. Family history was unremarkable. The child’s height was 92 cm, and her weight was 10 kg (both below the third percentile). She was growing consistently below the third percentile; the upper and lower ratios were within the reference range. She had no dysmorphic features. Physical examination revealed no specific findings.
