During the exam, the pediatrician notes that the child’s face lacks expression, has a short neck with excessive skin, a low hairline, low set ears, and a short broad nose (Figure 226-1). The child is appropriate for weight but his height is well below the third percentile. An audible systolic ejection murmur is heard. The pediatrician refers the child to a pediatric cardiologist who makes the diagnosis of pulmonic stenosis from physical exam and echocardiogram. Based on these findings, the pediatrician and cardiologist make a clinical diagnosis of Noonan syndrome, which is confirmed by genetic testing. A multidisciplinary approach to the child’s care is planned.
