Article Abstract
Mowat-Wilson syndrome (MWS) is an autosomal dominant genetic disorder caused by ZEB2 gene mutations, manifesting with unique facial characteristics, moderate to severe intellectual problems, and congenital malformations as Hirschsprung disease, genital and ophthalmological anomalies, and congenital cardiac anomalies. Herein, a case of 1-year-old boy with isolated agenesis of corpus callosum (IACC) in the prenatal period is presented. He was admitted postnatally with Hirschsprung disease (HSCR), hypertelorism, uplifted earlobes, deeply set eyes, frontal bossing, oval-shaped nasal tip, ''M'' shaped upper lip, opened mouth and prominent chin, and developmental delay. Hence, MWS was primarily considered and confirmed by the ZEB2 gene mutation analysis. His karyotype was normal. He had a history of having a prenatally terminated brother with similar features. Antenatally detected IACC should prompt a detailed investigation including karyotype and microarray; even if they are normal then whole exome sequencing (WES) should be done.

Mowat‒Wilson syndrome (MWS), a rare genetic disorder caused by heterozygous loss-of-function mutations in ZEB2, is characterised by significant growth retardation with unclear mechanisms. In this study, we developed a Zeb2 haploinsufficient (Zeb2) mouse model that recapitulates key features of MWS, including reduced body weight, impaired intestinal development and skeletal hypoplasia. RNA sequencing revealed significant downregulation of nutrient digestion and absorption pathways in the duodenum of Zeb2 mice, which was associated with reduced body fat and bone mass loss.

Nerve injury is a pathological condition characterized by damage or necrosis of nerve cells in injured areas due to trauma, infection, ischemia, genetic factor or other factors. Neural injury repair is precisely regulated by the complex regulatory network of body. Zinc finger E-box-binding protein 2 (ZEB2), known as a critical transcription factor, not only serves as a key participant in embryonic neural development, but also exerts a vital regulatory role in neural injury repair.

Mowat-Wilson syndrome (MOWS) is a congenital disease characterized by intellectual disability, delayed motor development, characteristic facial features, epilepsy, and a wide spectrum of neurocristopathies. MOWS is caused by de novo heterozygous loss-of-function mutations or deletions in the zinc finger E-box-binding homeobox2 (ZEB2) gene, which is a multifunctional regulator of neuronal development and cancer progression/metastasis through epithelial-to-mesenchymal transition. We recognized that patients with MOWS have brown to red hair.

Mowat-Wilson Syndrome is an autosomal dominant disorder caused by de novo heterozygous mutations of on 2q22. It is characterized by developmental delay, Hirschsprung's disease, seizures, and a wide variety of malformations affecting the neurologic, cardiac, and genitourinary systems. Reports describing the findings of Mowat-Wilson Syndrome at autopsy are sparse.
