Array-CGH detection of a de novo 2.8 Mb deletion in 2q24.2→q24.3 in a girl with autistic features and developmental delay

We report a 3 years and 4 months old girl with autistic features, developmental delay, mental retardation, language impairment and dysmorphic features, carrying a 2.8 Mb de novo deletion of chromosome 2q24.2→q24.3 detected by array-CGH. This region contains two neuronal voltage-gated sodium channel genes SCN2A and SCN3A.
