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]

Pathogenic, no assertion criteria provided	literature only	OMIM	Jan 01, 2010	- -
Benign, no assertion criteria provided	curation	Reproductive Health Research and Development, BGI Genomics	Jan 06, 2020	The ZEB1 gene is known as TCF8 in the published literature (PMID: 20036349). TCF8NM_030751.5:c.233A>C in the ZEB1 gene has an allele frequency of 0.052 in African subpopulation in the gnomAD database. 30 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. In addition, Riazuddin et al. reported a patient with Late-Onset Fuchs Corneal Dystrophy barboring p.N78T (PMID: 20036349). These evidence suggest the variant to be classified as benign. ACMG/AMP criteria applied: BA1. -

While the frequency of the alternate allele in gnoMAD v2.0.2 is 0.083, its frequency in African populations is >5%. This suggests that previous classifications of this variant as pathogenic are in error. -
