In 3 of 5 members with MODY (125850) in 1 family, Furuta et al. (1997) identified an arg127-to-trp (R127W) mutation resulting from a transition from CGG to TGG. The mutation was located in the T-box, a region of the protein that may play a role in HNF-4-alpha dimerization and DNA binding. The findings in the family suggested that the R172W mutation was not the only cause of diabetes. The overall results suggested that mutations in the HNF4A gene may cause early onset NIDDM/MODY in Japanese but such mutations are less common than mutations in the HNF1A/MODY3 gene (142410).
