ABSTRACT
OBJECTIVE@#To identify pathogenic variants in two patients with suspected for Mowat-Wilson syndrome (MWS).@*METHODS@#Genomic DNA was extracted from peripheral blood samples of the patients and his family members, and gene variants were analysis by Trio-whole exome sequences and copy number variation sequencing.@*RESULTS@#Patient 1 was found to carried a de novo heterozygous c.2769C>A (p.Y923*) nonsense variant of ZEB2 gene. The variant was not found in his healthy parents and sister. Patient 2 carried a de novo heterozygous frameshift variant of the ZEB2 gene, namely c.315delC (p.A105Afs*3), which has not been previously reported. Both variants were predicted to be pathogenic and can lead to premature occurrence of stop codons.@*CONCLUSION@#The heterozygous c.2769C>A (p.Y923*) and c.315delC (p.A105Afs*3) variants of the ZEB2 gene probably underlay the pathogenesis in the two patients. Gene testing has facilitated confirmation of the diagnosis and genetic counselling.
