Prenatal phenotype of molecularly confirmed MTDPS13 has not been well studied.<\/jats:p><\/jats:sec><jats:sec><jats:label\/><jats:p>This is the case report of a non\u2010consanguineously conceived fetus ascertained first at 20\u00a0weeks of gestation with multiple soft markers. Follow\u2010up fetal ultrasonogram at 26\u00a0weeks revealed periventricular cysts, periventricular echogenicity, ventriculomegaly, thin corpus callosum, mega cisterna magna, and large cavum. Fetal MRI confirmed these findings. Postnatally, the baby had clinical and biochemical findings indicative of a mitochondriopathy and died on neonatal day 3. Whole exome sequencing on stored amniotic fluid DNA confirmed the diagnosis of encephalomyopathic mitochondrial DNA depletion syndrome\u201013 (MTDPS13). This report presents the prenatal phenotype of this rare mitochondriopathy, which has been recognized primarily in postnatal patients. The brain imaging findings in the reported fetus indicate that MTDPS13 is associated with progressive neurological involvement and brain tissue destructive changes starting as early as the second trimester of pregnancy. The case also raises concerns regarding the association of so\u2010called soft markers, which were the only initial finding in this case, with severe monogenic diseases.<\/jats:p><\/jats:sec>","DOI":"10.1002\/pd.6272","type":"journal-article","created":{"date-parts":[[2022,11,22]],"date-time":"2022-11-22T04:24:47Z","timestamp":1669091087000},"page":"1682-1685","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Prenatal phenotype of <i>FBXL4<\/i>\u2010associated encephalomyopathic mitochondrial DNA depletion syndrome\u201013"],"prefix":"10.1002","volume":"42","author":[{"given":"Neelam","family":"Saini","sequence":"first","affiliation":[{"name":"Department of Medical Genetics Nizam's Institute of Medical Sciences Hyderabad  Hyderabad India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Venkatapuram","family":"Vijayasree","sequence":"additional","affiliation":[{"name":"Department of Medical Genetics Nizam's Institute of Medical Sciences Hyderabad  Hyderabad India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eshwar Chandra","family":"Nandury","sequence":"additional","affiliation":[{"name":"Department of Radiology Yashoda Hospitals Hyderabad  Hyderabad India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ashwin","family":"Dalal","sequence":"additional","affiliation":[{"name":"Diagnostics Division Centre for DNA Fingerprinting and Diagnostics  Hyderabad India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shagun","family":"Aggarwal","sequence":"additional","affiliation":[{"name":"Department of Medical Genetics Nizam's Institute of Medical Sciences Hyderabad  Hyderabad India"},{"name":"Diagnostics Division Centre for DNA Fingerprinting and Diagnostics  Hyderabad India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,11,26]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/humu.23341"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10545\u2010015\u20109836\u20106"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.3389\/fgene.2019.00039"},{"key":"e_1_2_9_5_1","first-page":"1993","volume-title":"GeneReviews\u00ae [Internet]","author":"Almannai M","year":"2017"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/ccr3.511"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/cge.12894"}],"container-title":["Prenatal Diagnosis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/pd.6272","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/pd.6272","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/pd.6272","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,8,20]],"date-time":"2023-08-20T16:48:52Z","timestamp":1692550132000},"score":1,"resource":{"primary":{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/10.1002\/pd.6272"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,11,26]]},"references-count":6,"journal-issue":{"issue":"13","published-print":{"date-parts":[[2022,12]]}},"alternative-id":["10.1002\/pd.6272"],"URL":"https:\/\/doi.org\/10.1002\/pd.6272","archive":["Portico"],"relation":{},"ISSN":["0197-3851","1097-0223"],"issn-type":[{"value":"0197-3851","type":"print"},{"value":"1097-0223","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,11,26]]},"assertion":[{"value":"2022-10-10","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2022-11-17","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2022-11-26","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
