Expanding the Genetic and Phenotypic Spectrum of Mowat-Wilson Syndrome: A Study of 10 Turkish Patients With an Intrafamilial Recurrence Caused by First Intragenic Large Deletion.

Mowat-Wilson syndrome (MWS) is a complex disorder caused by heterozygous ZEB2 gene variations creating haploinsufficiency. The main clinical features are evolving facial dysmorphism, intellectual disability, eye and brain malformations, and various organ anomalies. Our study examines 10 Turkish patients, who had clinical diagnosis, underwent evaluation, clinical investigations, and genetic tests in multiple tertiary centers across Türkiye, and were molecularly diagnosed with MWS.
