Genes affected

ZEB1 (HGNC:11642): (zinc finger E-box binding homeobox 1) This gene encodes a zinc finger transcription factor. The encoded protein likely plays a role in transcriptional repression of interleukin 2. Mutations in this gene have been associated with posterior polymorphous corneal dystrophy-3 and late-onset Fuchs endothelial corneal dystrophy. Alternatively spliced transcript variants encoding different isoforms have been described.[provided by RefSeq, Mar 2010]

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 10-31502425-C-T is Pathogenic according to our data. Variant chr10-31502425-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 2028102.Status of the report is criteria_provided_single_submitter, 1 stars.

For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with ZEB1-related conditions. This variant is present in population databases (rs772364498, gnomAD 0.003%). This sequence change creates a premature translational stop signal (p.Gln133*) in the ZEB1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ZEB1 are known to be pathogenic (PMID: 16252232, 17935237, 30851240). -
