Molecular mechanisms of congenital hyperinsulinism due to autosomal dominant mutations in ABCC8.
Congenital Hyperinsulinism (CHI) is a rare heterogeneous disease characterized by unregulated insulin secretion. Dominant mutations in ABCC8 causing medically unresponsive CHI have been reported; however, the molecular mechanisms are not clear. The molecular basis of medically unresponsive CHI due to dominant ABCC8 mutations has been studied in 10 patients, who were medically unresponsive to di...
متن کاملMolecular mechanisms of congenital hyperinsulinism.
Congenital hyperinsulinism (CHI) is a complex heterogeneous condition in which insulin secretion from pancreatic β-cells is unregulated and inappropriate for the level of blood glucose. The inappropriate insulin secretion drives glucose into the insulin-sensitive tissues, such as the muscle, liver and adipose tissue, leading to severe hyperinsulinaemic hypoglycaemia (HH). At a molecular level, ...
متن کاملNovel Hypoglycemia Phenotype in Congenital Hyperinsulinism Due to Dominant Mutations of Uncoupling Protein 2.
Context The rarest genetic form of congenital hyperinsulinism (HI) has been associated with dominant inactivating mutations in uncoupling protein 2 (UCP2), a mitochondrial inner membrane carrier that modulates oxidation of glucose vs amino acids. Objective To evaluate the frequency of UCP2 mutations in children with HI and phenotypic features of this form of HI. Design We examined 211 child...
متن کاملClinical characteristics and biochemical mechanisms of congenital hyperinsulinism associated with dominant KATP channel mutations.
Congenital hyperinsulinism is a condition of dysregulated insulin secretion often caused by inactivating mutations of the ATP-sensitive K+ (KATP) channel in the pancreatic beta cell. Though most disease-causing mutations of the 2 genes encoding KATP subunits, ABCC8 (SUR1) and KCNJ11 (Kir6.2), are recessively inherited, some cases of dominantly inherited inactivating mutations have been reported...
متن کاملMolecular mechanisms of autosomal dominant and recessive distal renal tubular acidosis caused by SLC4A1 (AE1) mutations
Mutations of SLC4A1 (AE1) encoding the kidney anion (Cl(-)/HCO(3) (-)) exchanger 1 (kAE1 or band 3) can result in either autosomal dominant (AD) or autosomal recessive (AR) distal renal tubular acidosis (dRTA). The molecular mechanisms associated with SLC4A1 mutations resulting in these different modes of inheritance are now being unveiled using transfected cell systems. The dominant mutants kA...
