HNF1B

MIM.189907 17cen-q21.3

Wednesday 20 April 2005

Definition: Hepatocyte nuclear factor-1-beta (HNF1B), also known as transcription factor-2 (TCF2), is a member of the homeodomain-containing superfamily of transcription factors.

Expression

Early expression of TCF2 is seen in the kidney, liver, bile ducts, thymus, genital tract, pancreas, lung, and gut. It can act either as a homodimer or as a heterodimer with HNF1A (MIM.142410).

The transcription factor hepatocyte nuclear factor HNF1B (TCF2) is expressed from the earliest stages of development of the Wolffian duct, the mesonephros and metanephros, and the Mullerian ducts in the mouse.

Functions

Hepatocyte nuclear factor-1beta (HNF-1beta) is a critical transcription factor in pancreatic and renal development.

HNF1B is a widely distributed transcription factor which plays a critical role in embryonic development of the kidney, pancreas, liver, and Mullerian duct.

The transcription factor hepatocyte nuclear factor (HNF)-1beta (HNF1B) is expressed from the earliest stages of development of the Wolffian duct, the mesonephros and metanephros, and the Müllerian ducts in the mouse.

In adult mice, HNF-1beta is expressed in the kidney tubules, collecting ducts, and in the oviducts and uterus in the female (Müllerian duct derivatives) and in the epididymis, vas deferens and seminal vesicles (Wolffian duct derivatives) in the male.

Pathology

HNF-1beta mutations have been reported in families where affected members have renal abnormalities, female genital tract malformations and early-onset diabetes. Renal and uterine abnormalities have not been described in families without early-onset diabetes.

Thirty HNF-1beta mutations have been reported in patients with renal cysts and other renal developmental disorders, young-onset diabetes, pancreatic atrophy, abnormal liver function tests, and genital tract abnormalities.

Mutations: HNF1B-V61G, HNF1B-V110G, HNF1B-S148L, HNF1B-K156E, HNF1B-Q176X, HNF1B-R276Q, HNF1B-S281fsinsC, HNF1B-R295P, HNF1B-H324fsdelCA, HNF1B-Q470X. 30% of de novo mutations. (15930087)

Mutant phenotype (15930087)

- renal cysts
- glomerulocystic kidney disease (GCKD)
- diabetes

  • maturity-onset diabetes of the young (MODY)
  • renal cysts and diabetes (RCAD)

No clear genotype/phenotype relationships. (15930087)

Despite the original description of HNF-1beta as a MODY gene, a personal/family history of diabetes is often absent and the most common clinical manifestation is renal cysts. (15930087)

Molecular genetic testing for HNF-1beta mutations should be considered in patients with unexplained renal cysts (including GCKD), especially when associated with diabetes, early-onset gout, or uterine abnormalities. (15930087)

Pathology

- HNF1B germline mutation in

  • MODY type V (MODY5) (MIM.604284)
    • MODY5 (MIM.604284) with mullerian aplasia (vaginal aplasia and rudimentary uterus) (MIM.158330)
    • MODY5 (MIM.604284) with nephron agenesis

- HNF1B deletions

  • HNF-1beta mutations have been identified 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 (RCAD) syndrome.
  • HNF-1beta gene deletions have recently been shown to cause renal malformations and early-onset diabetes.
  • The phenotype associated with deletions or coding region/splicing mutations is very similar suggesting that haploinsufficiency is the underlying mechanism. (17971380)

- HNF1B (TCF2) inactivation in tumors in chromophobe renal cell carcinoma

  • germline and somatic biallelic TCF2 (HNF1beta) inactivation in chromophobe renal cell carcinoma (MIM.144700) (15649945)
  • germline 1-bp deletion at nucleotide 46 (46delC) of the HNF1B gene, resulting in a frameshift and premature truncation at codon 17

- Underexpression of hepatocyte nuclear factor-1β in chromophobe renal cell carcinoma. (23237209)

  • Chromophobe renal cell carcinoma (ChRCC) is an uncommon malignant renal neoplasm with a generally indolent clinical behaviour.
  • Previous studies revealed biallelic inactivation of the hepatocyte nuclear factor-1β (HNF1β) gene in several patients with ChRCC.
  • A lack of HNF1β expression might play an important role in the pathogenesis of ChRCC, and may serve as a good diagnostic marker for this neoplasm.
