Our understanding of this disorder continues to improve as we identify more genes and gene variants associated with NPHP. In this report, we present a young patient with newly diagnosed advanced renal impairment and a strong family history of ESRD at a young age. The patient\u2019s kidney biopsy showed features suggestive of severe chronic interstitial nephritis, along with histopathological findings of advanced renal disease. Genetic testing revealed a novel variant in the\n                    <jats:italic>IQCB1<\/jats:italic>\n                    \/NPHP5 gene, which is autosomal recessive. Family genetic analysis revealed that the patient\u2019s parents and two of his children are heterozygous for the identified variant, while two siblings with ESRD are homozygous for the\n                    <jats:italic>IQCB1<\/jats:italic>\n                    p.(Ala486Asp) variant.

We report this novel gene variant in a Saudi family, describe its associated clinical features, and present the results of the family segregation analysis.\n                  <\/jats:p>","DOI":"10.1155\/crig\/1453255","type":"journal-article","created":{"date-parts":[[2025,4,29]],"date-time":"2025-04-29T02:48:28Z","timestamp":1745894908000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Novel NPHP5 Gene Mutation in Three Siblings With Nephronophthisis Without Retinitis Pigmentosa: A Case Report"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8331-407X","authenticated-orcid":false,"given":"Randah Abdullah","family":"Dahlan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roaa Hani","family":"Fairoozy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,4,28]]},"reference":[{"key":"e_1_2_8_1_2","doi-asserted-by":"publisher","DOI":"10.1053\/j.ajkd.2020.08.012"},{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00467-023-06096-5"},{"key":"e_1_2_8_3_2","first-page":"1993","volume-title":"GeneReviews\u00ae [Internet]","author":"Stokman M.","year":"2016"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1038\/ng1520"},{"key":"e_1_2_8_5_2","doi-asserted-by":"publisher","DOI":"10.2215\/CJN.01280217"},{"key":"e_1_2_8_6_2","doi-asserted-by":"publisher","DOI":"10.3390\/genes12111762"},{"key":"e_1_2_8_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-12-449851-8.00025-5"},{"key":"e_1_2_8_8_2","doi-asserted-by":"publisher","DOI":"10.1001\/archophthalmol.2010.330"},{"key":"e_1_2_8_9_2","doi-asserted-by":"publisher","DOI":"10.1111\/febs.14080"},{"key":"e_1_2_8_10_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00467-015-3068-8"},{"key":"e_1_2_8_11_2","doi-asserted-by":"publisher","DOI":"10.1002\/mgg3.2076"},{"key":"e_1_2_8_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.kint.2018.02.030"},{"key":"e_1_2_8_13_2","doi-asserted-by":"publisher","DOI":"10.1111\/pin.12292"},{"key":"e_1_2_8_14_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1523-1755.63.6s.2.x"},{"key":"e_1_2_8_15_2","doi-asserted-by":"publisher","DOI":"10.1093\/hmg\/ddt100"},{"key":"e_1_2_8_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.stemcr.2022.08.006"}],"container-title":["Case Reports in Genetics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/crig\/1453255","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1155\/crig\/1453255","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/crig\/1453255","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,8]],"date-time":"2026-03-08T11:05:39Z","timestamp":1772967939000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1155\/crig\/1453255"}},"subtitle":[],"editor":[{"given":"Balraj","family":"Mittal","sequence":"additional","affiliation":[],"role":[{"role":"editor","vocabulary":"crossref"}]}],"short-title":[],"issued":{"date-parts":[[2025,1]]},"references-count":16,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2025,1]]}},"alternative-id":["10.1155\/crig\/1453255"],"URL":"https:\/\/doi.org\/10.1155\/crig\/1453255","archive":["Portico"],"relation":{},"ISSN":["2090-6544","2090-6552"],"issn-type":[{"value":"2090-6544","type":"print"},{"value":"2090-6552","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,1]]},"assertion":[{"value":"2024-11-15","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-04-15","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-04-28","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"1453255"}}
