Deficiencies in SLC25A36 in mouse embryonic stem cells have been associated with mtDNA depletion as well as mitochondrial dysfunction. In human beings, diseases triggered by SLC25A36 mutations have not been described yet. We report the first known case of SLC25A36 deficiency in a 12-year-old patient with hypothyroidism, hyperinsulinism, hyperammonemia, chronical obstipation, short stature, along with language and general developmental delay. Whole exome analysis identified the homozygous mutation c.803dupT, p.Ser269llefs*35 in the SLC25A36 gene. Functional analysis of mutant SLC25A36 protein in proteoliposomes showed a virtually abolished transport activity. Immunoblotting results suggest that the mutant SLC25A36 protein in the patient undergoes fast degradation. Supplementation with oral uridine led to an improvement of thyroid function and obstipation, increase of growth and developmental progress. Our findings suggest an important role of SLC25A36 in hormonal regulations and oral uridine as a safe and effective treatment.<\/jats:p>","DOI":"10.3390\/ijms22189929","type":"journal-article","created":{"date-parts":[[2021,9,14]],"date-time":"2021-09-14T21:47:21Z","timestamp":1631656041000},"page":"9929","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Uridine Treatment of the First Known Case of SLC25A36 Deficiency"],"prefix":"10.3390","volume":"22","author":[{"given":"Luisa","family":"Jasper","sequence":"first","affiliation":[{"name":"Department of Pediatrics, University Hospital of M\u00fcnster, Albert-Schweitzer-Campus 1, Geb\u00e4ude A13, 48149 M\u00fcnster, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6216-0411","authenticated-orcid":false,"given":"Pasquale","family":"Scarcia","sequence":"additional","affiliation":[{"name":"Department of Biosciences, Biotechnologies and Biopharmaceutics, University of Bari, Via Orabona 4, 70125 Bari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephan","family":"Rust","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, University Hospital of M\u00fcnster, Albert-Schweitzer-Campus 1, Geb\u00e4ude A13, 48149 M\u00fcnster, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7220-7594","authenticated-orcid":false,"given":"Janine","family":"Reunert","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, University Hospital of M\u00fcnster, Albert-Schweitzer-Campus 1, Geb\u00e4ude A13, 48149 M\u00fcnster, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ferdinando","family":"Palmieri","sequence":"additional","affiliation":[{"name":"Department of Biosciences, Biotechnologies and Biopharmaceutics, University of Bari, Via Orabona 4, 70125 Bari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thorsten","family":"Marquardt","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, University Hospital of M\u00fcnster, Albert-Schweitzer-Campus 1, Geb\u00e4ude A13, 48149 M\u00fcnster, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"689","DOI":"10.1007\/s00424-003-1099-7","article-title":"The mitochondrial transporter family (SLC25): Physiological and pathological implications","volume":"447","author":"Palmieri","year":"2004","journal-title":"Pflugers Arch."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"465","DOI":"10.1016\/j.mam.2012.05.005","article-title":"The mitochondrial transporter family SLC25: Identification, properties and physiopathology","volume":"34","author":"Palmieri","year":"2013","journal-title":"Mol.
