Germline mutations in hepatocyte nuclear factor 1alpha (TCF1/HNF-1alpha) are associated with maturity-onset diabetes of the young type 3 (MODY3), and somatic biallelic inactivations of the gene are found in hepatocellular adenomas and liver adenomatosis.
Mutations in the transcription factor hepatocyte nuclear factor-1alpha (HNF-1alpha; gene symbol TCF1) cause maturity-onset diabetes of the young type 3 (MODY3), a form of diabetes mellitus characterized by autosomal dominant inheritance, early onset, and pancreatic beta-cell dysfunction.
Recently, hepatocyte nuclear factor-1alpha(HNF-1alpha, which is encoded by the TCF1 gene) mutations were reported in a subset of patients with maturity onset diabetes of the young (MODY3).
Here we show that subjects with the MODY3-form of NIDDM have mutations in the gene encoding hepatocyte nuclear factor-1alpha (HNF-1alpha, which is encoded by the gene TCF1).
