GNAS: A New Nephrogenic Cause of Inappropriate Antidiuresis
Nephrogenic syndrome of inappropriate antidiuresis (NSIAD) is the mirror image of nephrogenic diabetes insipidus (NDI): in NDI, the kidneys cannot concentrate the urine, whereas in
NSIAD, urinary dilution is impaired, independent of the presence or absence of vasopressin. Consequently, patients with NDI are at risk of hypernatremic dehydration, whereas
hyponatremia is a typical manifestation of NSIAD, mimicking the syndrome of inappropriate antidiuresis.
