Neuropsychological profile of Italian children and adolescents with 22q11.2 deletion syndrome with and without intellectual disability.

As individuals with chromosome 22q11.2 deletion syndrome (22q11DS) show a wide range of IQs, intellectual heterogeneity could mask the neuropsychological profile of the syndrome. This study was designed to identify specific neuropsychological features of children and adolescents with 22q11DS by taking into account the possible source of variability deriving from intellectual disability (ID).
