The 3 most cited genes describing microtia genetics alone were HOXA2, MUC6, and GSC. A single article describing nonsyndromic CAA alone identified the TSHZ1 as a candidate gene. Among 194 subjects from 18 manuscripts describing mendelian inheritance for non\u2010syndromic microtia or microtia and CAA, 49% of the individuals were found to have autosomal dominant transmission, 4% had autosomal recessive, 5% had X\u2010linked recessive, and 42% had no reported pattern of inheritance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Current literature on the genetics of microtia and CAA is largely derived from genetic analysis of syndromic patients. Despite comprising over half of the clinical population, available data on non\u2010syndromic patients remains limited. Understanding genetic polymorphisms and their correlation to phenotypic data more readily available to otolaryngologists offers the prospect of categorizing severity of anatomic malformation and hearing loss to guide future intervention, and improve ability to provide patient\u2010 and family\u2010centered counseling.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/ohn.1060","type":"journal-article","created":{"date-parts":[[2024,12,3]],"date-time":"2024-12-03T04:59:42Z","timestamp":1733201982000},"page":"811-820","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Genetics of Nonsyndromic Microtia and Congenital Aural Atresia: A Scoping Review"],"prefix":"10.1002","volume":"172","author":[{"given":"Aparna","family":"Govindan","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery University of Miami Miami Florida USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carly","family":"Fiest","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery Icahn School of Medicine at Mount Sinai New York New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David W.","family":"Chou","sequence":"additional","affiliation":[{"name":"Division of Facial Plastic and Reconstructive Surgery, Department of Otolaryngology\u2013Head and Neck Surgery Emory University School of Medicine Atlanta Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mia","family":"Saade","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery Rutgers New Jersey Medical School Newark New Jersey USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingyang","family":"Gray","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery Icahn School of Medicine at Mount Sinai New York New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maura","family":"Cosetti","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery Icahn School of Medicine at Mount Sinai New York New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,12,3]]},"reference":[{"key":"e_1_2_10_2_1","unstructured":"AndrewsJ KopaczAA HohmanMH.
