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]

Collection Method: curation

The ZEB1 gene is known as TCF8 in the published literature (PMID: 20036349). NM_030751.5:c.2519A>C in the ZEB1 gene has an allele frequency of 0.033 in European (Finnish) subpopulation in the gnomAD database. 22 homozygous occurrences are observed in the gnomAD database. Since the Fuchs Corneal Dystrophy was reported as Late-Onset, we determined to not apply the number of homozygousity as a strong benign evidence. Gupta et al reported an individual with fuchs endothelial corneal dystrophy harboing this variant (PMID: 26622166). In addition, Riazuddin et al. reported segregation of p.Q840P mutation in a large, multigenerational FCD pedigree, and concluded this allele to be sufficient but not necessary for pathogenesis. However, the author also stated that a second, independent genetic event might account for the phenotype in the other patients having not this variant (PMID: 20036349). We interpret it as variant of uncertain significance (VUS). ACMG/AMP criteria applied: BS1, PP4. -
