Symptoms Associated With Noonan Syndrome

Delayed Growth

While the birthweight of patients with Noonan syndrome is typically within the normal range, they usually experience delayed growth during childhood. Patients often have inadequate growth hormone levels, and they may experience feeding difficulties, leading to poor nutrition and problems with weight gain. Puberty may be delayed, and the growth spurt generally expected around this time is also often delayed. However, since Noonan syndrome also results in delays with achieving bone maturity, patients may continue growing throughout their late teenage years. Some patients are able to attain normal height by adulthood, and others may remain shorter than their peers. In addition to delayed physical growth, a small percentage of Noonan syndrome patients may experience mild developmental delays as well. Children with this condition can usually attend mainstream school, and they may sometimes need an individualized education plan.
