We report a case of a 2\u2010year\u2010and\u20108\u2010month\u2010old male, the seventh child of consanguineous parents, who presented with recurrent fever, febrile tonic\u2010clonic seizures, and periorbital edema. His medical history included multiple hospitalizations in infancy due to suspected sepsis and chest infections. Upon admission, laboratory findings revealed proteinuria, hypoalbuminemia, and hypercholesterolemia, along with mild hepatomegaly. Genetic testing identified compound heterozygous mutations (R138X and E130K) in the NPHS2 gene, confirming a diagnosis of HSRNS. Renal biopsy revealed features consistent with minimal change disease, and immunofluorescence was negative for IgG, IgM, IgA, C3, and C4. The patient was treated with enalapril as part of supportive management. This case highlights the importance of early genetic testing and renal biopsy in diagnosing steroid\u2010resistant nephrotic syndrome, particularly in children with atypical presentations. Understanding the genetic underpinnings of such rare cases is essential for guiding appropriate treatment and providing prognostic insights.<\/jats:p>","DOI":"10.1155\/crin\/8289305","type":"journal-article","created":{"date-parts":[[2026,1,30]],"date-time":"2026-01-30T07:40:18Z","timestamp":1769758818000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A
