Noonan syndrome is a genetic condition that can affect the heart, growth, blood clotting, and mental and physical development. Noonan et al. examined the stature of men and women with Noonan syndrome. The study contained 29 male and 44 female adults. One of the cut-off values used to assess the stature was the third percentile of adult height. 24 of the females fell below the third percentile of female adult height and 11 of the males fell below the third percentile of adult male height.
