Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_014795.4(ZEB2):c.2083C>T(p.Arg695Ter) variant causes a stop gained change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. R695R) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Pathogenic, criteria provided, single submitter | clinical testing | 3billion | Feb 23, 2023 | The variant is not observed in the gnomAD v2.1.1 dataset. This variant was predicted to result in a loss or disruption of normal protein function through nonsense-mediated decay (NMD) or protein truncation. Multiple pathogenic variants are reported downstream of the variant. The variant has been reported at least twice as pathogenic with clinical assertions and evidence for the classification (ClinVar ID: VCV000004755 / PMID: 11592033). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. - |

Pathogenic, criteria provided, single submitter | curation | Broad Center for Mendelian Genomics, Broad Institute of MIT and Harvard | Jan 25, 2023 | The p.Arg695Ter variant in ZEB2 was identified by our study in one individual with global developmental delay and agenesis of the corpus callosum. Trio exome analysis showed this variant to be de novo. The p.Arg695Ter variant in ZEB2 has been previously reported in 16 unrelated individuals with Mowat Wilson syndrome (PMID: 33510600, PMID: 32196960, PMID: 27831545, PMID: 15908750, PMID: 11592033, PMID: 31285160, PMID: 26809768, PMID: 11279515, PMID: 17932455, PMID: 24401652). The number of reported affected individuals with this variant is greater than expected compared to non-affected individuals with this variant. This variant was found to be de novo in 7 individuals with confirmed paternity and maternity (PMID: 33510600, PMID: 15908750, PMID: 11592033, PMID: 11279515, PMID: 24401652). This variant has also been reported in ClinVar (Variation ID: 4755) 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 695, 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_VeryStrong, PS4, PM2_Supporting (Richards 2015). - |
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 18, 2020 | For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in ZEB2 are known to be pathogenic (PMID: 16053902). This variant has been observed in several individuals affected with Mowat-Wilson syndrome (PMID: 27831545, 17932455, 26809768, 19842203, 17958891) including many de novo observations (PMID: 11592033, 15908750, 24401652, 26993267). This variant is also known as c.2083C>T (p.R925X), and this gene is also known as the SIP1 and ZFHX1B in the literature. ClinVar contains an entry for this variant (Variation ID: 4755). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Arg695*) in the ZEB2 gene. It is expected to result in an absent or disrupted protein product. - |
