Accurate molecular diagnosis is essential for distinguishing MODY from type 1 and type 2 diabetes, enabling precision\u2010based management and targeted therapy.

The identification of novel\n                      <jats:italic>GCK<\/jats:italic>\n                      variants and the detection of rare subtypes further expand the mutational and phenotypic spectrum of pediatric monogenic diabetes. These findings highlight the importance of incorporating population\u2010specific genomic data into clinical practice and of periodically re\u2010evaluating gene\u2013disease associations as new molecular and functional evidence emerges. Ultimately, the integration of molecular diagnostics into routine pediatric diabetes care will enhance diagnostic yield, optimize management, and improve long\u2010term outcomes for affected families.\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1155\/pedi\/4035026","type":"journal-article","created":{"date-parts":[[2025,12,1]],"date-time":"2025-12-01T12:01:37Z","timestamp":1764590497000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Revealing Monogenic Diabetes: Clinical and Genetic Features of Pediatric MODY Cases in T\u00fcrkiye: Single Center Experience"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1898-0898","authenticated-orcid":false,"given":"Aslihan","family":"Sanri","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7702-8296","authenticated-orcid":false,"given":"Tugba Kontbay","family":"Cetin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emel Gul","family":"Acikgoz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7745-8165","authenticated-orcid":false,"given":"Mehmet Burak","family":"Mutlu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5727-7965","authenticated-orcid":false,"given":"Ozlem","family":"Sezer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,12,1]]},"reference":[{"key":"e_1_2_9_1_2","doi-asserted-by":"publisher","DOI":"10.1002\/dme.1996.13.s6.90"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.4093\/jkd.2022.23.3.157"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13098-020-00557-9"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.2147\/DMSO.S179793"},{"key":"e_1_2_9_5_2","unstructured":"NaylorR.
