beta-Cell transcription factor genes are important in the pathophysiology of the beta-cell, with mutations in hepatocyte nuclear factor (HNF)-1alpha, HNF-4alpha, insulin promoter factor (IPF)-1, HNF-1beta, and NeuroD1/BETA2, all resulting in early-onset type 2 diabetes. We assessed the relative contribution of these genes to early-onset type 2 diabetes(More)
Heterozygous mutations in the gene that encodes the transcription factor hepatocyte nuclear factor 1β (HNF1B) represent the most common known monogenic cause of developmental kidney disease. Renal cysts are the most frequently detected feature of HNF1B-associated kidney disease; however, other structural abnormalities, including single kidneys and renal(More)
The transcription factor hepatocyte nuclear factor 1beta (HNF1beta) is a tissue-specific regulator that also plays an essential role in early development of vertebrates. In humans, four heterozygous mutations in the HNF1beta gene have been identified that lead to early onset of diabetes and severe primary renal defects. The degree and type of renal defects(More)
OBJECTIVES 'Persistent cloaca' is a severe malformation affecting females in which the urinary, genital and alimentary tracts share a single conduit. Previously, a Uroplakin IIIA (UPIIIA) mutation was reported in one individual with persistent cloaca, and UPIIIA, Sonic Hedgehog (SHH), Ephrin B2 (EFNB2) and Hepatocyte Nuclear Factor 1beta (HNF1beta) are(More)
The homeobox transcription factor hepatocyte nuclear factor 1beta (HNF1beta) is a tissue-specific regulator that plays an essential role in early vertebrate development. In humans, heterozygous mutations in the HNF1beta gene are associated with young-onset diabetes as well as a variety of disorders of renal development with cysts as the most consistent(More)
BACKGROUND Hepatocyte nuclear factor-1 beta (HNF-1beta) is a widely distributed transcription factor which plays a critical role in embryonic development of the kidney, pancreas, liver, and Mullerian duct. Thirty HNF-1beta mutations have been reported in patients with renal cysts and other renal developmental disorders, young-onset diabetes, pancreatic(More)
Mutations in hepatocyte nuclear factor 1B (HNF1B), which is a transcription factor expressed in tissues including renal epithelia, associate with abnormal renal development. While studying renal phenotypes of children with HNF1B mutations, we identified a teenager who presented with tetany and hypomagnesemia. We retrospectively reviewed radiographic and(More)
Familial glomerulocystic kidney disease (GCKD) is a dominantly inherited condition characterized by glomerular cysts and variable renal size and function; the molecular genetic etiology is unknown. Mutations in the gene encoding hepatocyte nuclear factor (HNF)-1beta have been associated with early-onset diabetes and nondiabetic renal disease-particularly(More)
BACKGROUND Familial juvenile hyperuricemic nephropathy (FJHN) is a dominantly inherited condition characterized by young-onset hyperuricemia, gout, and renal disease. The etiologic genes are unknown, although a locus on chromosome 16 has been identified in some kindreds. Mutations in the gene encoding hepatocyte nuclear factor (HNF)-1beta have been(More)
BACKGROUND Hepatocyte nuclear factor-1beta (HNF-1beta) is a critical transcription factor in pancreatic and renal development. Our previous report identified HNF-1beta mutations in 23/160 patients with unexplained renal disease. The most common phenotype is renal cysts, which is frequently associated with early-onset diabetes in the renal cysts and diabetes(More)
