Binder et al. [9] demonstrated that patients with SHOX deletion have shortened arm span for age, as well as one characteristic radiological sign of Leri-Weill-dyschondrosteosis, and concluded that these would be reasonable features to trigger initial SHOX gene testing in a patient with idiopathic short stature. The gene discussed is SHOX; the disease is Leri-Weill dyschondrosteosis.
