Here we describe a 2-year-old Japanese boy who exhibited typical clinical features of HI at birth. He survived beyond the neonatal period after oral retinoid treatment and, at the age of 2 years, showed moderately thick, lamellar scales and erythroderma over his whole body. The patient is a compound heterozygote for 2 &lt;i&gt;ABCA12&lt;\/i&gt; mutations, a paternal deletion mutation c.2021_2022del (p.Lys674ArgfsX63) and a novel maternal nonsense mutation c.7444C \u2192 T (p.Arg2482X). Electron microscopic observation of a skin biopsy specimen from the perinatal period revealed epidermal ultrastructural features consistent with HI. Immunofluorescence labeling using antiserum against a C-terminal ABCA12 epitope showed loss of expression in the patient\u2019s epidermis. The present patient demonstrates that rapid diagnosis of HI by ABCA12 expression analysis and mutation detection, and early commencement of systemic retinoid therapy are crucial to significantly improving an HI patient\u2019s prognosis.<\/jats:p>","DOI":"10.1159\/000104269","type":"journal-article","created":{"date-parts":[[2007,8,8]],"date-time":"2007-08-08T15:14:40Z","timestamp":1186586080000},"page":"155-159","source":"Crossref","is-referenced-by-count":15,"title":["Compound Heterozygous &lt;i&gt;ABCA12&lt;\/i&gt; Mutations Including a Novel Nonsense Mutation Underlie Harlequin Ichthyosis"],"prefix":"10.1159","volume":"215","author":[{"given":"Masashi","family":"Akiyama","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaori","family":"Sakai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshihiro","family":"Sato","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James R.","family":"McMillan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maki","family":"Goto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daisuke","family":"Sawamura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Shimizu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2007,8,8]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.jdermsci.2006.01.003"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1172%2FJCI24834"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1086%2F429844"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016%2FS0190-9622%2889%2980029-5"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1046%2Fj.1365-2133.1996.d01-1019.x"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1046%2Fj.1365-4362.2001.01173.x"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1038%2Fsj.jid.5700295"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1365-2133.2006.07434.x"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1093%2Fhmg%2Fddg235"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1146%2Fannurev.biochem.71.102301.093055"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.molmed.2005.06.004"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016%2FS0022-2836%2802%2901105-1"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1016%2FS0005-2736%2899%2900161-3"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1056%2FNEJMoa032178"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1001%2Farchderm.142.7.914"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1159%2F000069811"}],"container-title":["Dermatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/104269","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/104269","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T02:53:11Z","timestamp":1745463191000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000104269"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007]]},"references-count":16,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2007,8,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000104269","archive":["Portico"],"relation":{},"ISSN":["1018-8665","1421-9832"],"issn-type":[{"type":"print","value":"1018-8665"},{"type":"electronic","value":"1421-9832"}],"subject":[],"published":{"date-parts":[[2007]]}}}
