A genome-wide scan in families with maturity-onset diabetes of the young: evidence for further genetic heterogeneity.

Maturity-onset diabetes of the young (MODY) is a heterogeneous single gene disorder characterized by non-insulin-dependent diabetes, an early onset and autosomal dominant inheritance. Mutations in six genes have been shown to cause MODY. Approximately 15-20% of families fitting MODY criteria do not have mutations in any of the known genes.

Hepatocyte nuclear factor-1beta: a new kindred with renal cysts and diabetes and gene expression in normal human development.

The hepatocyte nuclear factor-1beta (HNF-1beta) transcription factor controls endoderm development. Human mutations cause early-onset diabetes mellitus and have recently been associated with dysplastic, hypoplastic, and glomerulocystic kidneys. A new kindred with this "renal cysts and diabetes" syndrome is described, and nephrogenic HNF-1beta expression is defined.
