Here, we describe a situation in which keratin 14 (K14) is missing altogether in the epidermis: A homozygous 2-nucleotide deletion in exon I of the K14 gene causes premature termination of the mRNA transcripts upstream from the start of the rod domain and results in a K14 null phenotype. In this individual no keratin intermediate filaments are visible in basal epidermal cells, although filaments are present in the upper layers of the epidermis. No compensating keratin expression is detected in vivo, and K14 mRNA is down-regulated. The individual, diagnosed as K\u00f6bner (generalized) EBS, suffers from severe widespread keratinocyte fragility and blistering at many body sites, but although the phenotype is severe, it is not lethal. This K14-\/- phenotype confirms that only one K14 gene is expressed in human epidermis and provides an important model system for examining the interdependence of different keratin filament systems and their associated structures in the skin.<\/jats:p>","DOI":"10.1101\/gad.8.21.2563","type":"journal-article","created":{"date-parts":[[2007,6,5]],"date-time":"2007-06-05T21:15:46Z","timestamp":1181078146000},"page":"2563-2573","source":"Crossref","is-referenced-by-count":150,"title":["A functional \"knockout\" of human keratin 14."],"prefix":"10.1101","volume":"8","author":[{"given":"E L","family":"Rugg","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"W H","family":"McLean","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E B","family":"Lane","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R","family":"Pitera","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J R","family":"McMillan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P J","family":"Dopping-Hepenstal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H A","family":"Navsaria","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I M","family":"Leigh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R A","family":"Eady","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"246","published-online":{"date-parts":[[1994,11,1]]},"reference":[{"key":"2021111418183241000_8.21.2563.1","doi-asserted-by":"publisher","DOI":"10.1083\/jcb.105.2.791"},{"key":"2021111418183241000_8.21.2563.2","doi-asserted-by":"publisher","DOI":"10.1083\/jcb.108.4.1477"},{"key":"2021111418183241000_8.21.2563.3","doi-asserted-by":"publisher","DOI":"10.1083\/jcb.115.6.1675"},{"key":"2021111418183241000_8.21.2563.4","doi-asserted-by":"publisher","DOI":"10.1101\/gad.7.7a.1191"},{"key":"2021111418183241000_8.21.2563.5","doi-asserted-by":"crossref","first-page":"37","DOI":"10.1242\/jcs.83.1.37","article-title":"Intermediate filament proteins in classic and variant types of small cell lung carcinoma cell lines : A biochemical and immunochemical analysis using a panel of monoclonal and polyclonal antibodies.","volume":"83","year":"1986","journal-title":"J.
