Behavioral abnormalities may also be observed, as well as variable facial and other dysmorphic features (such as broad nasal bridge, hypertelorism, almond-shaped eyes, high-arched palate, and anomalies of the fingers and toes). Brain imaging may reveal dilated ventricles, small corpus callosum, or posterior fossa abnormalities. |
