Significance Wolfram syndrome is a rare multisystem disease characterized by diabetes insipidus, diabetes mellitus, optic nerve atrophy, and deafness (DIDMOAD). It is primarily caused by mutations in the Wolfram syndrome 1 gene, WFS1 . As a monogenetic disorder, Wolfram syndrome is a model for diabetes and neurodegeneration. There is no effective treatment for this invariably fatal disease. Here we characterize WFS1 as a regulator of calcium homeostasis and subsequently target calcium signaling to reverse deficits in a cellular model of Wolfram syndrome.
