We describe a 6-year-old male patient with severe early onset manifestation of optic atrophy, whose parents are subjectively asymptomatic. OPA1-sequence analysis revealed the heterozygous missense variant NM_015560.3:c.806C&gt;T, p.(Ser269Phe) in the patient. Segregation analysis of the parents showed that the mother carried a low-grade postzygotic mosaic of this variant, which apparently also involves germline cells. In line with this, ophthalmological investigation of the mother showed subclinical manifestation of optic atrophy 1. This is the first report of an OPA1 postzygotic mosaic that was inherited to offspring.<\/jats:p>","DOI":"10.3390\/genes13030478","type":"journal-article","created":{"date-parts":[[2022,3,8]],"date-time":"2022-03-08T12:35:37Z","timestamp":1646742937000},"page":"478","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["First Description of Inheritance of a Postzygotic OPA1 Mosaic Variant"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2233-8734","authenticated-orcid":false,"given":"Svenja","family":"Alter","sequence":"first","affiliation":[{"name":"Institute of Human Genetics, Medical Center-University of Freiburg, Faculty of Medicine, University of Freiburg, 79106 Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4409-2176","authenticated-orcid":false,"given":"Navid","family":"Farassat","sequence":"additional","affiliation":[{"name":"Eye Center, Medical Center-University of Freiburg, Faculty of Medicine, University of Freiburg, 79106 Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0758-5120","authenticated-orcid":false,"given":"Sebastian","family":"K\u00fcchlin","sequence":"additional","affiliation":[{"name":"Eye Center, Medical Center-University of Freiburg, Faculty of Medicine, University of Freiburg, 79106 Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wolf A.","family":"Lagr\u00e8ze","sequence":"additional","affiliation":[{"name":"Eye Center, Medical Center-University of Freiburg, Faculty of Medicine, University of Freiburg, 79106 Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8580-8118","authenticated-orcid":false,"given":"Judith","family":"Fischer","sequence":"additional","affiliation":[{"name":"Institute of Human Genetics, Medical Center-University of Freiburg, Faculty of Medicine, University of Freiburg, 79106 Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"E692","DOI":"10.1002\/humu.21025","article-title":"Molecular Screening of 980 Cases of Suspected Hereditary Optic Neuropathy with a Report on 77 Novel OPA1 Mutations","volume":"30","author":"Bonneau","year":"2009","journal-title":"Hum.
