Alpha-thalassemia

An inherited hemoglobinopathy characterized by impaired synthesis of alpha-globin chains leading to a variable clinical picture depending on the number of affected alleles.

Short stature

A height below that which is expected according to age and gender norms. Although there is no universally accepted definition of short stature, many refer to \"short stature\" as height more than 2 standard deviations below the mean for age and gender (or below the 3rd percentile for age and gender dependent norms).
