However, the impact of a heterozygous CFTR mutation in a patient with trisomy 21 remains unexplored. We present a male infant with trisomy 21 who experienced recurrent respiratory distress and was later found to carry a heterozygous pathogenic CFTR mutation (p.Phe508del). His respiratory complications were severe, requiring tracheostomy and long\u2010term respiratory support. This case highlights the potential interplay between trisomy 21\u2010associated anatomical features and CFTR\u2010related airway abnormalities, possibly exacerbating respiratory morbidity. Given the high burden of respiratory complications in both conditions, clinicians should consider CFTR\u2010related disorders in patients with trisomy 21 presenting with severe respiratory issues. Further research is warranted to determine the clinical significance of CFTR heterozygosity in trisomy 21 and its implications for disease severity and management.<\/jats:p>","DOI":"10.1002\/rcr2.70185","type":"journal-article","created":{"date-parts":[[2025,4,16]],"date-time":"2025-04-16T05:58:07Z","timestamp":1744783087000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Novel Co\u2010Occurrence of Trisomy 21 and Heterozygous <scp>CFTR<\/scp> Mutation"],"prefix":"10.1002","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-2564-5781","authenticated-orcid":false,"given":"Majd","family":"Oweidat","sequence":"first","affiliation":[{"name":"College of Medicine Hebron University  Hebron, West Bank Palestine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tamer","family":"Qutaina","sequence":"additional","affiliation":[{"name":"College of Medicine Hebron University  Hebron, West Bank Palestine"},{"name":"Department of Pediatrics Al\u2010Ahli Hospital  Hebron, West Bank Palestine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-1590-8024","authenticated-orcid":false,"given":"Alzahra Akram","family":"Hamdan","sequence":"additional","affiliation":[{"name":"College of Medicine Hebron University  Hebron, West Bank Palestine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-2927-2403","authenticated-orcid":false,"given":"Fatima Zain","family":"Hanini","sequence":"additional","affiliation":[{"name":"College of Medicine Hebron University  Hebron, West Bank Palestine"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,4,15]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcf.2022.01.009"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/humu.23389"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpeds.2007.09.045"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469\u20100705.1999.13030167.x"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12929\u2010015\u20100138\u2010y"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/0753\u20103322(94)90140\u20106"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00431\u2010022\u201004634\u20101"},{"key":"e_1_2_9_9_1","volume-title":"Genetic Disorders","author":"D B.","year":"2013"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1093\/ofid\/ofy219"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1152\/ajplung.00434.2020"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcf.2010.05.003"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/S2213\u20102600(22)00504\u20105"}],"container-title":["Respirology Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/rcr2.70185","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,29]],"date-time":"2025-04-29T02:55:21Z","timestamp":1745895321000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/rcr2.70185"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,4]]},"references-count":12,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2025,4]]}},"alternative-id":["10.1002\/rcr2.70185"],"URL":"https:\/\/doi.org\/10.1002\/rcr2.70185","archive":["Portico"],"relation":{},"ISSN":["2051-3380","2051-3380"],"issn-type":[{"value":"2051-3380","type":"print"},{"value":"2051-3380","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,4]]},"assertion":[{"value":"2025-02-28","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-04-07","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-04-15","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e70185"}}
