MODY5 diabetes

MODY5 diabetes is an autosomal dominant disorder of glucose metabolism and kidney development. The disease is caused by mutations of TCF2 gene better known as HNF1-beta.

Test Strategy

In families with kidney dysplasias and type 2 diabetes this disease can be suspected. This suspicion would further supported if there is no association with metabolic syndrome in diabetic individuals.


The gene codes a transcription factor that is involved in cell regulation during kidney development and insulin secretion.


Hypomagnesemia is observed in most of the patients with MODY5 though it is not a symptom that dominates the clinical picture.
Malformations of the urinary tract
Malformations in MODY 5 are predominantly cystic. Because apparent soon after birth, they precede diabetes.
