They usually have a below-borderline normal IQ, with most individuals having higher scores in the verbal than the nonverbal domains. No evidence for an effect of COMT valto-met genotype on executive function in patients with 22q11 deletion syndrome.

Their velocardilfacial patients were diagnosed mainly through their pattern of facial dysmorphism and only 2 and 4 of the 8, respectively, had clefts and heart defects. No cure is known for DiGeorge syndrome.

VCFS patients showed deviations mostly in the posterior part of the dorsum sellae, and patients had increased cranial base angles compared to controls. Based on symptoms and genetic testing [5].
