Nonsense mutation of islet-1 gene (Q310X) found in a type 2 diabetic patient with a strong family history.

Abstract excerpt

Islet-1 (Isl-1) is one of the transcription factors that play an important role for the formation of the islet cells. We scanned the Isl-1 gene in 77 Japanese type 2 diabetic patients with a family history and found a heterozygous nonsense mutation (Q310X) in 1 diabetic patient. The mutation was not found in 180 nondiabetic subjects. This mutation is located in the putative transactivation domain and deletes 40...
