Abstract

Neurodevelopmental disorders are a group of diseases characterized by either structural or functional alterations. The clinical spectrum can vary from isolated intellectual disability to more complex syndromes. Molecular karyotyping can explain 14%-18% of cases due to the presence of large pathogenic CNVs. Moreover, small CNVs involving single genes might result in a monogenic disease. In this article we report two cases of intragenic CTNND2 deletion, detected by molecular karyotyping, in patients with isolated intellectual disability.
