Neurodevelopmental disorders (NDDs) are a heterogeneous class of brain diseases, with a complex genetic basis estimated to account for up to 50% of cases. Nevertheless, genetic diagnostic yield is about 20%. Array-comparative genomic hybridization (array-CGH) is an established first-level diagnostic test able to detect pathogenic copy number...

The KCNQ5 gene, widely expressed in the brain, encodes a voltage-gated potassium channel (Kv7.5) important for neuronal function. Here, we report a novel KCNQ5 intragenic duplication at 6q13 spanning about 239 Kb of genomic DNA, identified by array comparative genomic hybridization (array-CGH). The duplication was found in heterozygosity in an...

Background: Noonan syndrome (NS) is a genetic multisystem disorder characterised by variable clinical manifestations including dysmorphic facial features, short stature, congenital heart disease, renal anomalies, lymphatic malformations, chest deformities, cryptorchidism in males.Methods: In this narrative review, we summarized the available...

Introduction: Nowadays, whole-exome sequencing (WES) analysis is an essential part in the diagnostic pathway of individuals with complex phenotypes when routine exams, such as array-CGH and gene panels, have proved inconclusive. However, data on the diagnostic rate of WES analysis in adult individuals, negative to first-tier tests, are lacking....
