The genetic basis of this disease has been shown to be due to mutations in the WFS1 gene. The WFS1 gene encodes a novel transmembrane protein called wolframin, which recent evidence suggests may serve as a novel endoplasmic reticulum calcium channel in pancreatic \u03b2-cells and neurons. Genotype-phenotype correlations in this syndrome are becoming apparent and may help in explaining some of the variable characteristics observed in this disease.<\/jats:p>\n               <jats:p>RESEARCH DESIGN AND METHODS\u2014In this report, we have studied 13 patients with Wolfram syndrome from nine families to further define the relationship between mutation site and type with specific disease characteristics.<\/jats:p>\n               <jats:p>RESULTS\u2014A severe phenotype was seen in patients with mutations in exon 4 and with a large deletion encompassing most of exon 8. In total, nine novel mutations were identified as well as three new silent polymorphisms.<\/jats:p>\n               <jats:p>CONCLUSIONS\u2014Similar to all other mutation reports, most causative changes identified in the WFS1 gene occurred in exon 8, and only one was identified outside this region in exon 4.<\/jats:p>","DOI":"10.2337\/diacare.27.8.2003","type":"journal-article","created":{"date-parts":[[2007,3,5]],"date-time":"2007-03-05T22:51:27Z","timestamp":1173135087000},"page":"2003-2009","update-policy":"https:\/\/doi.org\/10.2337\/ada-journal-policies","source":"Crossref","is-referenced-by-count":86,"title":["Phenotype-Genotype Correlations in a Series of Wolfram Syndrome Families"],"prefix":"10.2337","volume":"27","author":[{"given":"Casey J.A.","family":"Smith","sequence":"first","affiliation":[{"name":"John Hunter Children\u2019s Hospital, University of Newcastle and the Hunter Medical Research Institute, New South Wales, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patricia A.","family":"Crock","sequence":"additional","affiliation":[{"name":"John Hunter Children\u2019s Hospital, University of Newcastle and the Hunter Medical Research Institute, New South Wales, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bruce R.","family":"King","sequence":"additional","affiliation":[{"name":"John Hunter Children\u2019s Hospital, University of Newcastle and the Hunter Medical Research Institute, New South Wales, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cliff J.","family":"Meldrum","sequence":"additional","affiliation":[{"name":"Division of Genetics, Hunter Area Pathology Service, John Hunter Hospital, Newcastle, New South Wales, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rodney J.","family":"Scott","sequence":"additional","affiliation":[{"name":"Division of Genetics, Hunter Area Pathology Service, John Hunter Hospital, Newcastle, New South Wales, Australia"},{"name":"Discipline of Medical Genetics, Faculty of Health, and the Hunter Medical Research Institute, University of Newcastle, New South Wales, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1167","reference":[{"key":"2022031216065898900_R1","doi-asserted-by":"crossref","unstructured":"Rotig A, Cormier V, Chatelain P, Francois R, Saudubray JM, Rustin P, Munnich A: Deletion of mitochondrial DNA in a case of early-onset diabetes mellitus, optic atrophy, and deafness (Wolfram syndrome, MIM 222300).
