Description

This sequence change creates a premature translational stop signal (p.Arg302*) in the ZEB2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ZEB2 are known to be pathogenic (PMID: 16053902). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individuals with Mowat-Wilson syndrome (PMID: 15121779, 19842203). ClinVar contains an entry for this variant (Variation ID: 160329). For these reasons, this variant has been classified as Pathogenic.

Description

The heterozygous p.Arg302Ter variant in ZEB2 was identified by our study in one individual with periventricular heterotopia, agenesis of the corpus callosum, and seizures. Trio exome analysis showed this variant to be de novo. The p.Arg302Ter variant in ZEB2 has been previously reported in at least 4 unrelated individuals with Mowat Wilson syndrome (PMID: 28096981, PMID: 29093530, PMID: 15121779, PMID: 19842203). The number of reported affected individuals with this variant is slightly greater than expected compared to non-affected individuals with this variant. This variant was found to be de novo in 2 individuals with confirmed paternity and maternity (PMID: 28096981, PMID: 29093530). This variant has also been reported in ClinVar (Variation ID: 160329) and has been interpreted as pathogenic by multiple submitters. This variant was absent from large population studies. This nonsense variant leads to a premature termination codon at position 302, which is predicted to lead to a truncated or absent protein. Heterozygous loss of function of the ZEB2 gene is an established disease mechanism in autosomal dominant Mowat Wilson syndrome. In summary, this variant meets criteria to be classified as pathogenic for Mowat Wilson syndrome. ACMG/AMP Criteria applied: PVS1, PS2, PS4_Moderate, PM2_Supporting (Richards 2015).
