Bichet DG et al. - Misfolded arginine-vasopressin V2 receptors are unable to reach the plasma membrane in principal collecting duct cells and to engage the circulating antidiuretic hormone, arginine-vasopressin. These misfolded proteins potentially could be rescued with pharmacologic chaperones, an active area of research pertinent to other hereditary protein misfolding diseases such as cystic fibrosis, phenylketonuria, and Anderson-Fabry disease among many others. Finally, a long-term careful surveillance of all patients with hereditary NDI should be performed to prevent chronic renal failure likely caused by the long-term functional tract obstruction with reflux.
