| A rare genetic developmental defect during embryogenesis syndrome with characteristics of agenesis of the corpus callosum, mild to severe neurological manifestations (intellectual disability, developmental delay, epilepsy, dystonia), and urogenital anomalies (hypospadias, cryptorchidism, renal dysplasia, ambiguous genitalia). Additionally skeletal anomalies (limb contractures, scoliosis), dysmorphic facial features (large eyes, prominent supraorbital ridges, synophrys) and optic atrophy have been observed. The disease is caused by mutation in the ARX gene. |
