As the cardinal symptoms of DI, polyuria and polydipsia, overlap with those of DM, DI might be underdiagnosed or delayed in the early stages of WS1. In the present study, we assessed whether DI could be an early sign of WS1 and analyzed genotype\u2013phenotype correlations in a group of Turkish patients with Type 1 DM.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Patients and Methods:<\/jats:bold>\n                    We applied a polyuria\/polydipsia questionnaire to 1278 children with Type 1 DM. Patients with suggestive symptoms of DI were further evaluated for other clinical features of WS1 and molecular genetic analysis of the\n                    <jats:italic>WFS1<\/jats:italic>\n                    gene. Clinical, laboratory, and genetic characteristics of cases identified using questionnaires were compared with a historical case series of seven children with WS1 and previously published literature data.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    Eighteen patients were considered to have a diagnosis of DI, thereby being eligible for genetic analysis of\n                    <jats:italic>WFS1<\/jats:italic>\n                    variants. Of those, six had biallelic variations (four missense variants, one in\u2010frame duplication, and three frameshift variants) in the\n                    <jats:italic>WFS1<\/jats:italic>\n                    gene, and a diagnosis of WS1 was confirmed. The age of admission for DM was younger in the historical cases (5.1\u2009\u00b1\u20092.0 vs. 8.7\u2009\u00b1\u20093.4;\n                    <jats:italic>p<\/jats:italic>\n                    = 0.04). There was no statistically significant difference between the ages for the diagnosis of WS1 (12.9\u2009\u00b1\u20095.0 vs. 9.6\u2009\u00b1\u20092.7;\n                    <jats:italic>p<\/jats:italic>\n                    = 0.191), though the diagnostic delay from DM onset to WS1 diagnosis was significantly shorter in the screened group (median 1.8 vs. 6.9 years;\n                    <jats:italic>p<\/jats:italic>\n                    \u2248 0.015).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusion:<\/jats:bold>\n                    Our findings suggest that DI may present before OA in WS1. Enriching the diagnosis of DI using a simple polyuria\/polydipsia questionnaire may provide an earlier diagnosis of WS1 in patients followed with Type 1 DM. Screening and early genetic testing of these patients enhances the diagnosis, follow\u2010up, and management strategies of patients with WS1.\n                  <\/jats:p>","DOI":"10.1155\/pedi\/8692152","type":"journal-article","created":{"date-parts":[[2025,10,2]],"date-time":"2025-10-02T09:04:39Z","timestamp":1759395879000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Diabetes Insipidus as an Early Clinical Indicator of Wolfram Syndrome Type 1: Evidence From a Symptom\u2010Based Screening Approach"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8117-6408","authenticated-orcid":false,"given":"Ozge Beyza","family":"Gundogdu Ogutlu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9776-555X","authenticated-orcid":false,"given":"Atilla","family":"Cay\u0131r","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7024-8157","authenticated-orcid":false,"given":"Ay\u015fe Sena","family":"Donmez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9724-2369","authenticated-orcid":false,"given":"Serkan Bilge","family":"Koca","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0107-5720","authenticated-orcid":false,"given":"Oguzhan","family":"Yarali","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6374-5884","authenticated-orcid":false,"given":"Huseyin","family":"Demirbilek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,10,2]]},"reference":[{"key":"e_1_2_11_1_2","doi-asserted-by":"crossref","unstructured":"WolframD.andWagenerH.
