HNF4A-associated hyperinsulinism

Monday 25 January 2010

Mutations of the hepatocyte nuclear factor 4-alpha (HNF4A) gene are associated with neonatal hyperinsulinaemic hypoglycaemia. (#19566570#)

Mutations of this gene also cause one of the subtypes of monogenic diabetes, a form of diabetes formerly known as maturity-onset diabetes of the young (MODY).

HNF4A gene is involved when neonate is macrosomic with maturity-onset diabetes of the youth (MODY) in relatives.

A frame-shift mutation of the HNF4A gene has been observed in the setting of early-onset maternal diabetes and severe neonatal hyperinsulinaemic hypoglycaemia. (#19566570#)
