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: clinical testing

The c.973C>T (p.R325*) alteration, located in exon 7 (coding exon 7) of the ZEB1 gene, consists of a C to T substitution at nucleotide position 973. This changes the amino acid from a arginine (R) to a stop codon at amino acid position 325. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. This variant was not reported in population-based cohorts in the Genome Aggregation Database (gnomAD). This variant was reported in individual(s) with features consistent with ZEB1-related posterior polymorphous corneal dystrophy (Aldave, 2007). Based on the available evidence, this alteration is classified as pathogenic.
