We describe an unusual presentation of PPCD associated with a previously unknown genetic alteration in the ZEB1 gene. The proband is a 64-year-old woman diagnosed with keratoconus referred for a corneal endothelium study who presented endothelial lesions in both eyes suggestive of PPCD, corectopia and iridocorneal endothelial synechiae in the right eye and intrastromal segments in the left eye. The endothelial count was 825 in the right eye and 1361 in the left eye, with typical PPCD lesions visible under specular and confocal microscopy. In the next generation sequencing genetic analysis, a heterozygous c.1A &gt; C (p.Met1Leu) mutation was found in the ZEB1 gene (TCF8). The PPCD3 subtype is associated with corneal ectasia, and both can appear due to a pathogenic mutation in the ZEB1 gene (OMIM #189909). However, our patient had a previously unreported mutation in the ZEB1 gene, which mediates the transition between cell lines and provides a pathogenic explanation for the epithelialisation of the corneal endothelium, a characteristic of PPCD.<\/jats:p>","DOI":"10.3390\/ijms24010209","type":"journal-article","created":{"date-parts":[[2022,12,23]],"date-time":"2022-12-23T02:09:03Z","timestamp":1671761343000},"page":"209","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Posterior Polymorphous Corneal Dystrophy in a Patient with a Novel ZEB1 Gene Mutation"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3381-4863","authenticated-orcid":false,"given":"Eva","family":"Fern\u00e1ndez-Guti\u00e9rrez","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, La Paz University Hospital, 28046 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5509-6359","authenticated-orcid":false,"given":"Pedro","family":"Fern\u00e1ndez-P\u00e9rez","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, La Paz University Hospital, 28046 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana","family":"Boto-De-Los-Bueis","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, La Paz University Hospital, 28046 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Garc\u00eda-Fern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Molecular Genetics Section, Medical and Molecular Genetics Institute (INGEMM) IdiPaz, La Paz University Hospital, 28046 Madrid, Spain"},{"name":"Biomedical Research Centre in the Rare Diseases Network (CIBERER), Carlos III Health Institute (ISCIII), 28029 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0118-5003","authenticated-orcid":false,"given":"Patricia","family":"Rodr\u00edguez-Solana","sequence":"additional","affiliation":[{"name":"Molecular Ophthalmology Section, Medical and Molecular Genetics Institute (INGEMM) IdiPaz, La Paz University Hospital, 28046 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mario","family":"Sol\u00eds","sequence":"additional","affiliation":[{"name":"Biomedical Research Centre in the Rare Diseases Network (CIBERER), Carlos III Health Institute (ISCIII), 28029 Madrid, Spain"},{"name":"Clinical Bioinformatics Section, Medical and Molecular Genetics Institute (INGEMM) IdiPaz, La Paz University Hospital, 28046 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8080-8629","authenticated-orcid":false,"given":"Elena","family":"Vallesp\u00edn","sequence":"additional","affiliation":[{"name":"Biomedical Research Centre in the Rare Diseases Network (CIBERER), Carlos III Health Institute (ISCIII), 28029 Madrid, Spain"},{"name":"Molecular Ophthalmology Section, Medical and Molecular Genetics Institute (INGEMM) IdiPaz, La Paz University Hospital, 28046 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,22]]},"reference":[{"key":"ref_1","first-page":"43","article-title":"La clasificaci\u00f3n IC3D de las distrofias corneales","volume":"27","author":"Weiss","year":"2008","journal-title":"C\u00f3rnea"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1029","DOI":"10.1093\/hmg\/11.9.1029","article-title":"VSX1: A gene for posterior polymorphous dystrophy and keratoconus","volume":"11","author":"Heon","year":"2002","journal-title":"Hum.
