Here we report an 18 month-old girl in whom we have identified the homozygous ABHD5 mutation c.700C &gt; T, p.(Arg234*). Since none of the parents carried this point mutation, parentage was confirmed by microsatellite marker analysis. Suspected uniparental disomy (UPD) was confirmed by microsatellite genotyping over the entire chromosome 3 and indicated a maternal origin. UPD is an extremely rare event that is not necessarily pathogenic, but may cause disease if the affected chromosome contains genes that are imprinted. Here we report the first case of Chanarin-Dorfman syndrome due to a de novo ABHD5 mutation in the maternal germ cell, combined with a maternal uniparental isodisomy of chromosome 3. This case demonstrates that genetic analysis of the patient and both parents is crucial to provide correct genetic counseling.<\/jats:p>","DOI":"10.3390\/genes12081164","type":"journal-article","created":{"date-parts":[[2021,7,29]],"date-time":"2021-07-29T02:18:24Z","timestamp":1627525104000},"page":"1164","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Maternal Isodisomy of Chromosome 3 Combined with a De Novo Mutation in the ABHD5 Gene Causes Autosomal Recessive Chanarin-Dorfman Syndrome"],"prefix":"10.3390","volume":"12","author":[{"given":"Julia","family":"Kopp","sequence":"first","affiliation":[{"name":"Institute of Human Genetics, Medical Center, Faculty of Medicine, University of Freiburg, 79106 Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cristina","family":"Has","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Faculty of Medicine, University Medical Center Freiburg, 79106 Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2560-3951","authenticated-orcid":false,"given":"Alrun","family":"Hotz","sequence":"additional","affiliation":[{"name":"Institute of Human Genetics, Medical Center, Faculty of Medicine, University of Freiburg, 79106 Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5986-0468","authenticated-orcid":false,"given":"Sarah C.","family":"Gr\u00fcnert","sequence":"additional","affiliation":[{"name":"Department of General Pediatrics, Adolescent Medicine and Neonatology, Faculty of Medicine, University Medical Center 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, Faculty of Medicine, University of Freiburg, 79106 Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"905","DOI":"10.1111\/liv.14794","article-title":"Chanarin-Dorfman Syndrome: A comprehensive review","volume":"41","author":"Cakmak","year":"2021","journal-title":"Liver Int."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"261","DOI":"10.1001\/archderm.1974.01630080059017","article-title":"Ichthyosiform Dermatosis with Systemic Lipidosis","volume":"110","author":"Dorfman","year":"1974","journal-title":"Arch.
