Five Red Angus-Simmental calves born over a 6-year period demonstrated severe hypotrichosis and were diagnosed as affected with ECTD1-like syndrome. Two died of severe pneumonia within a week of birth. The skin of three affected calves revealed a predominance of histologically unremarkable small-caliber hair follicles. Larger follicles (&gt;50 \u00b5m) containing medullated hairs (including guard and tactile hairs) were largely restricted to the muzzle, chin, tail, eyelids, tragus and distal portions of the limbs and tail. The mean histological density of hair follicles in flank skin of two affected calves was slightly greater than that in two unaffected calves. One affected calf was examined postmortem at 10 days of age to better characterize systemic lesions. Nasolabial, intranasal and tracheobronchial mucosal glands were absent, whereas olfactory glands were unaffected. Mandibular incisor teeth were absent. Premolar teeth were unerupted and widely spaced. Other than oligodontia, histological changes in teeth were modest, featuring multifocal disorganization of ameloblasts, new bone formation in dental alveoli, and small aggregates of osteodentin and cementum at the margins of the enamel organ. A 52,780 base pair deletion spanning six out of eight coding exons of EDA and all of AWAT2 was identified. Partial deletion of the EDA gene is the presumed basis for the reported X-chromosomal recessive inherited genodermatosis.<\/jats:p>","DOI":"10.3390\/ani11030657","type":"journal-article","created":{"date-parts":[[2021,3,2]],"date-time":"2021-03-02T04:42:46Z","timestamp":1614660166000},"page":"657","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["X-Linked Hypohidrotic Ectodermal Dysplasia in Crossbred Beef Cattle Due to a Large Deletion in EDA"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5174-8487","authenticated-orcid":false,"given":"Donal","family":"O\u2019Toole","sequence":"first","affiliation":[{"name":"Wyoming State Veterinary Laboratory, University of Wyoming, Laramie, WY 82070, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5648-963X","authenticated-orcid":false,"given":"Irene M.","family":"H\u00e4fliger","sequence":"additional","affiliation":[{"name":"Institute of Genetics, Vetsuisse Faculty, University of Bern, 3001 Bern, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fabienne","family":"Leuthard","sequence":"additional","affiliation":[{"name":"Institute of Genetics, Vetsuisse Faculty, University of Bern, 3001 Bern, Switzerland"},{"name":"Dermfocus, University of Bern, 3001 Bern, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brant","family":"Schumaker","sequence":"additional","affiliation":[{"name":"Wyoming State Veterinary Laboratory, University of Wyoming, Laramie, WY 82070, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lynn","family":"Steadman","sequence":"additional","affiliation":[{"name":"Chadron Veterinary Clinic, Chadron, NE 69337, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0057-0604","authenticated-orcid":false,"given":"Brian","family":"Murphy","sequence":"additional","affiliation":[{"name":"Department of Pathology, Microbiology and Immunology, School of Veterinary Medicine, University of California, Davis, CA 95616, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9773-522X","authenticated-orcid":false,"given":"Cord","family":"Dr\u00f6gem\u00fcller","sequence":"additional","affiliation":[{"name":"Institute of Genetics, Vetsuisse Faculty, University of Bern, 3001 Bern, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0553-4880","authenticated-orcid":false,"given":"Tosso","family":"Leeb","sequence":"additional","affiliation":[{"name":"Institute of Genetics, Vetsuisse Faculty, University of Bern, 3001 Bern, Switzerland"},{"name":"Dermfocus, University of Bern, 3001 Bern, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"70","DOI":"10.1002\/humu.21384","article-title":"Only four genes (EDA1, EDAR, EDARADD, and WNT10A) account for 90% of hypohidrotic\/anhidrotic ectodermal dysplasia cases","volume":"32","author":"Cluzeau","year":"2010","journal-title":"Hum.
