We herein describe a 37-year-old Japanese woman who manifested diabetic ketosis at the onset. The coexistence of features associated with MODY5, including abnormal renal function, impaired insulin secretion, pancreatic hypoplasia and hypomagnesemia, prompted us to decode her genomic information using whole-exome sequencing, where we were not able to identify any pathogenic <i>HNF1B</i> gene mutations. We further examined her genomic integrity using multiplex ligation probe amplification (MLPA) analysis, leading to identification of the 17q12 microdeletion which was further supported by array comparative genomic hybridization (array-CGH). Her insulin secretory capacity was insufficient, whereas her total daily dose of insulin was 11 U/day (0.25 U/Kg/day), indicating that she was relatively sensitive to insulin. As a possible explanation, we found that her plasma glucagon level was below the detection limit. Since inactivation of acetyl-CoA carboxylase 1 (<i>ACACA</i>), encoded in close proximity to the <i>HNF1B</i> gene, was reported to blunt glucagon secretion, the concurrent deletion of the <i>ACACA</i> gene may be in part responsible for this manifestation. In conclusion, the genetic analyses of MODY5 cases require the judicious use of appropriate genetic technologies. In addition, alpha-cell dysfunction may at least in part account for the variable clinical manifestations of MODY5.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s13340-025-00804-2.</p>","PeriodicalId":11340,"journal":{"name":"Diabetology International","volume":"16 2","pages":"432-438"},"PeriodicalIF":1.3,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11954765/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143751564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Type-2 diabetes mellitus (T2DM) is a chronic metabolic disorder affecting millions worldwide. It is a risk factor for cardiovascular disease.

Inflammation, oxidative stress, insulin resistance, and endothelial dysfunction are some of the mechanisms involved. Dipeptidyl peptidase-4 (DPP-IV) inhibitors may affect cardiac function by modulating inflammation and oxidative stress, affecting endothelial function, and modifying myocardial fibrosis.

However, DPP-IV inhibitors have been shown to lower glucose levels and alter HF risk in addition to their glucose-lowering effects. Sitagliptin is an oral medication used to treat T2DM. Sitagliptin is often used in combination with other diabetes medications. A preclinical study showed that sitagliptin improved cardiac function in models of heart failure. The precise mechanisms responsible for this improvement are not yet fully understood, but it could be related to inflammation and oxidative stress. Patients with T2DM are more prone to HF, which highlights the necessity of effective therapies to improve both blood glucose control and cardiovascular health.
