A consistent pattern was evident in the audiograms, with features of sensory presbycusis, cochlear origin at all levels of hearing loss, and a high degree of vulnerability of outer hair cells. That the degree of hearing loss was similar in affected subjects within the same sibling group but differed between sibling groups suggests the involvement of nuclear modifier genes. Total mitochondrial DNA sequences were completely identical among subjects with various levels of hearing loss, and lacked additional pathogenic mutations. For the diagnosis of sensorineural hearing loss, the mitochondrial A1555G mutation should be considered when these features are present even in the absence of aminoglycoside exposure.<\/jats:p>","DOI":"10.1177\/000348940511400213","type":"journal-article","created":{"date-parts":[[2014,10,3]],"date-time":"2014-10-03T14:40:52Z","timestamp":1412347252000},"page":"153-160","source":"Crossref","is-referenced-by-count":13,"title":["Audiological Features and Mitochondrial DNA Sequence in a Large Family Carrying Mitochondrial A1555G Mutation without Use of Aminoglycoside"],"prefix":"10.1177","volume":"114","author":[{"given":"Tatsuo","family":"Matsunaga","sequence":"first","affiliation":[{"name":"Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Kumanomido","sequence":"additional","affiliation":[{"name":"Tochigi, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu-ichi","family":"Goto","sequence":"additional","affiliation":[{"name":"Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masae","family":"Shiroma","sequence":"additional","affiliation":[{"name":"Tochigi, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shin-ichi","family":"Usami","sequence":"additional","affiliation":[{"name":"Matsumoto, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2005,2,1]]},"reference":[{"key":"bibr1-000348940511400213","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1098-1004(1999)13:4<261::AID-HUMU1>3.0.CO;2-W"},{"key":"bibr2-000348940511400213","doi-asserted-by":"publisher","DOI":"10.1038\/ng0793-289"},{"key":"bibr3-000348940511400213","doi-asserted-by":"publisher","DOI":"10.1021\/bi970962r"},{"key":"bibr4-000348940511400213","doi-asserted-by":"publisher","DOI":"10.1159\/000472169"},{"key":"bibr5-000348940511400213","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-199704000-00011"},{"key":"bibr6-000348940511400213","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.48.2.453"},{"key":"bibr7-000348940511400213","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1096-8628(19981012)79:5<388::AID-AJMG11>3.0.CO;2-N"},{"key":"bibr8-000348940511400213","doi-asserted-by":"publisher","DOI":"10.1086\/301676"},{"key":"bibr9-000348940511400213","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1996.01890210073016"},{"key":"bibr10-000348940511400213","unstructured":"Matsunaga T, Kumanomido H, Shiroma M, Delineation of the phenotypic expression in a large Japanese family with A1555G mitochondrial mutation.
