Popis: DeSanto-Shinawi syndrome (DESSH, OMIM #616708) is a rare autosomal dominant neurodevelopmental disorder caused by loss-of-function variants in the WAC gene. Affected individuals are characterized by neonatal hypotonia, developmental delay, intellectual disability, behavioral problems, and dysmorphism. Epilepsy is present in some of the patients with DESSH. By far, less than 30 affected individuals have been reported worldwide. Herein, we report a 9-year-old Chinese girl with molecularly substantiated DESSH with a de novo nonsense c. 1648C>T p.(Arg550*) variant identified in the WAC gene. Aside from developmental delay and the characteristic facial gestalt, our proband also exhibited tethered cord syndrome due to filar lipoma and left duplex kidney complicated with hydronephrosis, features not observed in any of the previously reported individuals with DESSH.
