We report the first case of a newborn girl presenting with multiple congenital anomalies and a double mosaic trisomy involving chromosome 14 and the X chromosome detected by array CGH.
Prematurity, ventricular septal defect and dysmorphisms are independent predictors of pathogenic copy number variants: a retrospective study on array-CGH results and phenotypical features of 293 children with neurodevelopmental disorders and/or multiple congenital anomalies.
Thus, our results support the use of array-CGH replacing standard karyotype as the first-tier cytogenetic diagnostic test for patients with multiple congenital anomalies and/or intellectual disability.
Array-CGH has revealed a large number of copy number variations (CNVs) in patients with multiple congenital anomalies and/or mental retardation (MCA/MR).
Using array CGH analysis, we have identified six overlapping microdeletions encompassing the FOX transcription factor gene cluster in chromosome 16q24.1q24.2 in patients with ACD/MPV and MCA.
