Core Tip

Core Tip: We describe a patient with maturity-onset diabetes of the young 3 caused by a splicing mutation in intron 5 at position 24 of chromosome 12, where the base sequence was replaced from G to A, and the protein encoded was changed accordingly. Excellent blood glucose control can be achieved by using low-dose sulfonylureas.
