Clinical Report: HNF1B-MODY (MODY-5): An Uncommon Diabetes Variant
Overview
This report presents two clinical cases of HNF1B-MODY, highlighting its systemic manifestations. The cases illustrate the diverse phenotypic spectrum associated with HNF1B mutations, including renal and genitourinary anomalies.
Background
MODY is a rare form of diabetes that often goes misclassified as type 1 or type 2 diabetes, leading to underdiagnosis. HNF1B-MODY, accounting for less than 5% of MODY cases, is characterized by early onset diabetes and significant extrapancreatic manifestations, including renal and genitourinary abnormalities.
Data Highlights
No numerical data or trial data presented in the article.
Key Findings
HNF1B-MODY is caused by mutations in the HNF1B gene and presents with diverse systemic manifestations.
Patients may exhibit renal abnormalities, including cysts, and genitourinary malformations.
Hypomagnesemia and abnormal liver function tests are common features in HNF1B-MODY.
Phenotypic variability exists among affected individuals, complicating diagnosis.
Clinical Implications
Clinicians should maintain a high index of suspicion for HNF1B-MODY in young patients with diabetes and associated renal or genitourinary anomalies.
Conclusion
The cases presented highlight the broad phenotypic spectrum of HNF1B-MODY in young-onset diabetes.
