title: Autosomal dominant familial neurohypophyseal diabetes insipidus.
abstract: Autosomal dominant familial neurohypophyseal diabetes insipidus (adFNDI) is a rare disorder caused by progressive postnatal arginine vasopressin (AVP) deficiency resulting from mutations in the AVP gene encoding the AVP pre-prohormone. It has been suggested that these mutations exert their effect on the cellular handling of the AVP prohormone by leading to the synthesis of mutant hormone precursor that fails to be processed and/or folded properly in the endoplasmic reticulum (ER). As a consequence, it is retained by the ER protein quality control machinery resulting in protein accumulation and initiation of cellular processes leading to degeneration of the AVP producing neuron. This review summarizes the current knowledge on adFNDI and discusses different hypotheses concerning its pathogenesis.
